[00:00:00]Hello.

[00:00:04]I mean chapter start going okay with the help of questions.

[00:00:08]I mean each and every concept.

[00:00:11]Okay.

[00:00:15]Also with the help of 30 question. Okay, 30 to my NCERT derived questions. I see now question number one is the best reagent to convert an alcohol to an alkyl chloride. Yeah, the question is the best reagent. Firstly to my This, this, this, this. But all of the four reagent that we use alcohol.

[00:00:36]Alcohol or product to me. I'm the most respective. This one alkyl chloride one one above a column I mean use column okay. Looking at my question is the best best reagent key over. I think the most NCERT book would be the unique dimension for I say. They tell me R O S plus S O C L 2 that they use for I know. Then they tell me product will have a to my R C L of course and this one alkyl chloride to will be able.

[00:01:00]Plus the my S O 2 or plus A C L will be able. I will able to take you home for I know these two are gases. I will able to take you home for I. The my reaction chamber of course. I will able to take you home for I will be able to take you home for I will be able to take you home for I will be able to I mean respective this one of.

[00:01:17]The product I mean by so. Okay, the my by product. Not take a more. I mean mixture of the my by product not take a more. Not by okay my I mean purely I mean product don't tell me. I mean by so I mean I mean I will be able to take.

[00:01:30]Okay.

[00:01:31]Finkelstein reaction is primarily used for the synthesis of. See first of all the my this question I feel important I will take you home for This is a name reaction okay. Name reaction question I.

[00:01:42]I see Finkelstein reaction is primarily used for the synthesis of what? I mean no Finkelstein and I will be able to take you home for I will be able to take you home for I mean alkyl halide or product I will be able to take you home for I will be able to take you home for I will be I will be able to take you home for I will be able to take you home for I will be I will be bromine or chlorine or bromine or chlorine or I mean Kiba no R I okay.

[00:02:08]I mean Finkelstein I mean name reaction reaction video then alkyl iodide okay alkyl iodide I see okay. Swartz reaction is specifically used to prepare a guide Swartz reaction I mean R X or R F or no okay. Specifically I mean alkyl fluoride or no.

[00:02:36]Sandmeyer reaction involves the use of which reagent? A check. I don't know what I'm going to do I guess you know with along with tricks. Yeah they have I mean this is benzene diazonium salt right? Yeah I don't know I mean the money I don't know what I'm going to do I mean this the method I say I don't know what I'm going to do I mean Sandmeyer reaction or I mean Gattermann Gattermann reaction. Now what is the difference in these two? Yeah they know the money copper has Sandmeyer at the country city mayor right? I mean I don't know what I'm going to do I mean body goes like you okay.

[00:03:18]I mean C U 2 X 2 Yeah they keep yeah they don't know what copper plus one or take it. And this is known as the money Sandmeyer Sandmeyer reaction I don't know I don't know what I'm going to do I mean copper tequila take it I don't know what I'm going to do I mean I don't know what I'm going to do I mean tequila take it I don't know what I'm going I don't know what I'm going to do I mean Gattermann reaction okay. Then I don't know what I'm going to do I mean C U 2 X 2 Now Gattermann reaction differs from Sandmeyer by using what? I mean copper powder use color okay.

[00:04:09]Now come to question number six. Which of the following halides is most reactive towards SN1 reaction?

[00:04:22]nucleophilic substitution unimolecular, okay? unimolecular This is the two-step reaction and it depends on the year to my to the my rate of reaction No, depends on only one only one this one only one molecule. Right?

[00:04:39]First first step attack or it is Okay?

[00:04:49]Now carbocation rate of reaction a tertiary secondary and then primary.

[00:05:00]Okay?

[00:05:02]rate of reaction RI, RBr or RCl, okay?

[00:05:08]If you rate of reaction I What is this I? I, Br, Cl These are the leaving group. What is the nucleo- nucleophile So I rate of rate of reaction He can do the my year to go to the RI.

[00:05:30]RI to my bond length will be okay. Bond length will be to this bond is little bit weak. Halka That is what I Br a bond strong is the bond length a a lot of total RCl a lot of bond will be total. Right?

[00:05:57]And now you have to do my carbocation intermediate form one. That piece of the car carbocation will do my carbocation one year.

[00:06:05]Now you get to my nucleophile to my that query one or the car carbocation to my the planar molecule because I don't have to let's just do the planar technique like queries it. So you find that you know my upper upper deck query one to my dollar per deck query one. Right? So you have to do my car at that to my manual at that D form for the like D form like if the molecule to my chiral one or that that to my D form a whole or at that L form L form will be able to do side of right to my deck query as a new query to my new online you put a bread at a query one. You got to do that type of isomer form one is it to him it I mean key comparison of racemic mixture isomerism of I see the one or at that to my at that compound or at that to my D form you have to like to my D form is it any good or that query one L form of a purpose any good or that query query to you have to inactive one idea. Okay, you have to make sure to my key of a optically inactive mixture of a to my racemic mixture good form of a to my SN1 reaction form one. Now come to SN2 reaction which is a single step reaction that to my at that step of that to my living group will I see the one or to my nucleophile I had a deck query one or that First of all you get to my living group will I see the one or those side of the product to with you see the one or nucleophile I had a deck query one or no query one or that to my steric hindrance bubble. Okay, I mean that about that bubble like you have to last to pay either you better better halogen here. Now you know he got to make query to my nucleophile which is a deck query one. Okay, so you got to make inversion with a bubble to my configuration will tell you see the one or right somebody had a to my intermediate form the way you have to do the math. Uh beach me here form where the five-member species that form where okay. Now, the rate of reaction to the car. The r i r b r and r c l are the same. Got any living group to my easily will I go human and I'm going to buy right? The other day the same take it all but the car into the primary alkyl halide secondary and tertiary alkyl halide. The primary alkyl alkyl halide both alkyl react Google cookie to my primary alkyl halide are special and better better group night right? To easily beat you say that Google that we should do my halide of easily will I do my Bible.

[00:08:22]I do my other day to my steady hindrance would come home. He going to do my primary secondary and tertiary. Uh I would like to SN 1 reaction to to my SN reaction medium of polar product solvent low. I do my SN 2 and my polar a product solvent use Google. Yeah, that you have a important important way I don't know what I do.

[00:08:43]I know Okay, see. Which of the following halides is most reactive towards SN 1?

[00:08:50]What is it like to my carbocation or stability for the kind of a to my carbocation or stability for the depend on it. The tertiary carbocation is most stable right?

[00:08:59]That we saw which of the following halides is most reactive towards SN 2?

[00:09:04]Okay, SN 2 to my SN steady hindrance sound okay here you can say that Google.

[00:09:09]To is Google like Google now.

[00:09:11]I suppose by the Google many say to get to to my primary alkyl halide with a Google. No, no primary to your total say here to my methyl. The Google you have to say something to Google say CH3 X I do the support to Google right now.

[00:09:23]I do primary on the other hand to my CH uh okay.

[00:09:29]Yeah, that methyl halide with a Google.

[00:09:31]Now, SN 1 reaction proceeds by the formation of what? To my carbocation okay you can do my carbocation or stability Google by the Google.

[00:09:42]>> What?

[00:09:52]Now, racemization is a characteristic of what which mechanism?

[00:10:07]Now, the elimination of HX from an alkyl halide is known as hydro to hydro halogenation.

[00:10:34]dehydrohalogenation simple Okay. Now, come to question number 12.

[00:10:42]According to the Saytzeff rule, the major product in dehydrohalogenation It will leave a double a double bond in the carbon chain. Okay.

[00:11:12]This reaction is a little bit important.

[00:11:14]This reagent, okay? To me alcoholic KOH, okay?

[00:11:38]>> Okay. Now, Okay.

[00:11:50]Now, Now, Which is more stable?

[00:11:55]Which is more stable?

[00:12:12]And this first stable alkene is known as the Saytzeff product.

[00:12:20]Who is the more substituted And this product is known as the Hofmann product. Okay.

[00:12:26]Hofmann product less substituted alkene.

[00:12:29]Done? Uh see.

[00:12:33]Uh highly substituted alkene. Okay. Now, Grignard reagents are chemically what?

[00:12:38]Grignard reagent RMgX. This is a very important uh the my reagent right. Okay.

[00:12:44]RMgX to give alkyl magnesium halide.

[00:12:49]The episode Wurtz-Fittig reaction.

[00:12:53]Uh the my Yeah, you don't know me up me go let it go, right?

[00:13:00]India uh the die RX RX And this one benzene a benzene a lot me uh this one halide loaded. Because it It can make Nothing. It's going to be free radical when I do It's going to be free radical when I do. And then I get a whole bunch of This is going to look like this. So, it will give all This is known as the alkyl benzene.

[00:13:26]Alkyl benzene. benzene.

[00:13:32]Simple to my alkyl alkyl.

[00:13:47]Now, the reaction of two molecules of chlorobenzene with sodium in dry ether gives what? See, this is the my reaction. This is the my reaction, okay?

[00:14:03]my biphenyl okay. This is known as my biphenyl or diphenyl diphenyl, okay?

[00:14:20]I do the my commonly naphthalene believe what I have.

[00:14:24]And this is the my biphenyl or diphenyl. Now, in Dow's process chlorobenzene is converted to phenol by heating with NaOH at given in NCERT because I like both my standard questions do to my local got to my chance that I get. See, I already my reaction condition is 623 Kelvin and 300 to 320 ATM, okay? 623 in 300 ATM.

[00:14:55]This one chlorobenzene key of phenol money, okay? Chlorobenzene to phenol. Now, this is also a method of preparation of what? Phenol, Now, a freon 20 12 a freon 12 a widely used refrigerant is what? This is nothing but chlorofluorocarbon, okay?

[00:15:16]Chlorofluorocarbon with the chlorine fluorine I say. See, CCl2F2. I do the my this one chapter of last of >> Now DDT is manufactured by the condensation of chlorobenzene with again to me you had to give my DDT to my data insecticide or organic insecticide okay it will only chloral hair color I mean condensation of chlorobenzene color okay Okay.

[00:15:55]I mean chloroform a formula to my CH uh CL3 right in the same way to my CH I 3 is to my iodoform okay.

[00:16:05]Now you have to get a common booster combine sign up this a CH CH group okay Yeah they like remember example who did you go by like my mobile camera to the software is low this question. Yeah they see the double bond O Right RC double bond O CH3 This group that guy doing I know uh the my agenda compound a two group I said they will give the positive iodoform test okay.

[00:16:29]Yeah they take what do my benzyl alcohol is it in a key night I'm structure like he said by night to my problem one or low tonight. Propanol of the mixture grow okay CH or uh CH3 see uh OH plus Yeah they can say CH three check see double yeah they like I can see I didn't mention this yet see double bond O yeah three to my secondary alcohol okay secondary alcohol or the my soluble Yes yeah they do my acid group done Yeah they do my tonight I don't like it like it check what he said by my papa okay. Then now chloroform is stored in dark colored bottles to prevent prevent its oxidation into See chloroform no chloroform do they have any like light up black one or poor horror key word I think it is the oxidized by start for you okay CH uh CL3 plus the more uh yeah, O2 oxidized Korean tomato highly poisonous gas form quality is known as phosgene. These are all given in NCERT.

[00:17:29]Remember my big fight yes, because it's a I'll see these are the polyhalogen compound. Okay. The methyl dichloro methane yeah, for uh methylene chloride will equal right.

[00:17:45]Okay. You have to do my trichloromethane. What is trichloromethane? Nothing but chloroform. You have to do my junior get a reaction yes, they I see chloroform plus O2 in the presence of light to my 2 COCL2 plus 2 HCL. This phosgene. This is to my highly poisonous. Um Um poisonous gas white like you will die. Okay, to me and I go to my money is about. Okay. I know to my Yeah, I guess my new is a signal. Uh I don't think so. These are that much important, but still Um and I do form I do form no CH uh CH3. It's a antiseptic white uh to my antiseptic white. Earlier I mean antiseptic is having used for a season. Remember? That is all to my I must say to my tetrachloride sky in my important night. Okay. Yeah, the arrows on his upper your refrigerator is having me used for a while.

[00:18:36]No, this freons take to my freons is freon 12 is to my CCl2F2. This is a chlorofluorocarbon.

[00:18:44]Okay, chlorofluorocarbon and my DDT is the first chlorinated organic insecticide. Okay.

[00:18:57]And Did you do my kitty money did you do my life life life could you buy no sorry for saying no? That they you had to master fish I say no fish. You had to do my DDT you had to guide here we go say to my accumulate accumulate going going no you had to Highly uh like Okay.

[00:19:20]General knowledge here that you have.

[00:19:23]And Okay.

[00:19:34]Okay.

[00:19:35]Okay.

[00:19:45]Okay.

[00:19:46]Uh now the uh the These are the Friedel-Crafts reaction. Simple.

[00:19:57]Okay.

[00:20:00]Okay.

[00:20:02]Now This is Dow's process. Uh this is uh Dow's process. Okay. Chlorobenzene in presence of NaOH uh harsh condition. Okay. Uh he do condition that you do more it do phenol form. Right? That episode that I I mean electron withdrawing group so no uh condition a little bit like a little bit of kind of uh Okay.

[00:20:41]I don't know what you say. Right?

[00:20:48]electron withdrawing group E chlorine like highly active activate quality. Okay.

[00:20:58]Simply uh substitute for you Okay.

[00:21:09]>> Okay.

[00:21:12]Okay, we are done with almost everything.

[00:21:28]Okay, it has to be the most C and Okay.

[00:21:42]nitrile or cyanide, okay.

[00:21:58]Okay.

[00:22:15]nitro alkane This one r o r o r o to my N C A Okay, we are done with the almost everything. I have a question to ask a question. Practice going to okay.

[00:22:48]Um, I check.

[00:22:49]Uh, the reaction of reaction of an alkyl halide with KCN predominantly gives what?

[00:22:59]Okay.

[00:23:04]Okay.

[00:23:08]isocyanide episode a reaction with KNO2 a double alkyl nitrite a nitroalkane Now, and an allylic halide has the halogen atom attached to an what What is allylic position? C double bond C C X This is known as the allylic position.

[00:23:45]double bonded carbon and local I would like the carbon like you see this is known as the allylic position. Okay. So, what is this? This is sp3 hybridized sp3 hybridized carbon next to a carbon carbon double bond. Okay. The benzene the whole thing Although the my benzene You know what the my double double double bond I say looking benzene or I mean they like come. Okay.

[00:24:05]I see question. Okay. A vinylic halide has the halogen atom. And what is vinylic position? This is known as the vinylic position. Okay.

[00:24:14]This is known as the vinylic position not this this.

[00:24:17]Okay. Yeah, the double local or no yeah, the carbon like this carbon will be called as the vinylic carbon. Okay, vinylic carbon. So, give it a What is this? This is sp2. sp2 carbon sp2 carbon of a carbon carbon carbon carbon double bond. Okay. Now, a benzylic halide has the halogen atom attached to Now, check what is benzylic halide. Check. Yeah, this CH2 X This is known as the my benzylic position. Okay. It is benzenol or directly attached to my into benzenol or what attached to a carbon or carbon or I mean you can call benzylic position.

[00:24:50]Okay. So, what is this? This is the my sp3 hybridized again sp3 hybridized next to a benzene ring. Okay.

[00:24:57]Now the my aryl halides are extremely less reactive towards nucleophilic substitution because of a what? See.

[00:25:04]This is known as aryl halide. The chlorine here I know chlorine or lone pair. The other must resonance resonance quality benzene or load. The carbon atom at the partial double bond character or is that this partial double bond character is the more You know hard to break and and this this carbon is the more sp2.

[00:25:27]sp2 carbon is more electronegative, no?

[00:25:29]You keep going electron pairs of both strongly much more you keep holding it is good break in the total motion if you don't mind all given in NCERT, okay? Do they do my mind that they break for you or is that okay? Okay, do my do my carbocation form of a no carbocation to my phenyl phenyl group of form of all this is known as the phenyl position, okay?

[00:25:54]Finally finally carbocation form of all and this is highly unstable. Yeah, positive to my sp2 hybridized carbon of the more positive charge is that this is very unstable. There are multiple reasons like to my to my multiple reasons is that they can do my first and foremost reason is to my partial double bond character of carbon halogen bond, okay?

[00:26:14]They can do my substitution reaction not going easily, okay? They can do my do they do my Dow's process going to know Dow's process do they do my both harsh condition local local animal. Which isomer of dichlorobenzene has the highest melting point? Of course, I mean do they do my melting point of all the melting point of all the I mean always any case of the more lattice structure of the more human perfectly arranged ways that okay do they do my better isomer no this chlorine and this chlorine this is known as the better better isomer it is perfectly do they do my arranged ways that perfectly arranged ways that they can do my is going to my melting point of all the high over high over better isomer, okay?

[00:26:54]And now melting point uh Oh.

[00:26:59]Um humble. All right.

[00:27:01]Now remember, chiral molecules are those which are what?

[00:27:09]A demonstration do you have beside you or what is chiral molecule? And Looking Is it a good layout game?

[00:27:24]Okay.

[00:27:26]Let me ask her Okay. I do superimposable on the non-superimposable or non-superimposable non-superimposable.

[00:27:37]Uh so, we are done with the chapter. Uh I hope What important are these chapters?

[00:27:43]Uh like uh revise again and again.

[00:27:51]Okay, bye-bye. Take care.
