[00:00:01]Hello.

[00:00:03]Okay. First of all, multiple revisions of question.

[00:00:22]Okay. Basically, I'll make you learn. Okay. like okay with the help of questions.

[00:00:51]Okay.

[00:01:03]Okay. And all the questions are derived.

[00:01:09]Okay. So, let's start.

[00:01:13]Okay.

[00:01:20]Okay.

[00:01:30]Okay.

[00:01:35]Okay. First, which of the following represents the general formula of hydrogen plus CN Okay. This is what see methan. Okay. Methan alken and alkon.

[00:02:25]Okay. CH3. CH3. Yeah. CH 2 double bond CH2 CH.

[00:02:38]Okay. Done.

[00:02:52]And second reaction involves the treatment of alkalhalides with okay. Although this is a name of first of all select H girlfriend X right.

[00:03:49]Okay.

[00:04:03]Now come the caroxilation of sodium.

[00:04:07]First of all, you must know right C N A E What is this? This is nothing but caroxyic acid. Okay. C N Aino sodium salt of ethaninoic acid. Okay.

[00:04:35]Right.

[00:04:45]Okay.

[00:04:59]Okay.

[00:05:03]Cannot be used to prepare. See this is similar to reaction. Okay. Step up not reduction step up reaction. Okay.

[00:05:24]Right.

[00:05:40]Okay. Cannot be used to prepare this.

[00:05:49]Which catalyst is used in free radicalation?

[00:05:52]Free radicalation.

[00:05:55]almost each and every chapter. Okay.

[00:06:01]Catalyst catalyst is nothing but anhydr3 this will be called as what elect.

[00:06:56]Okay. Now come to question number six.

[00:06:59]reacts with chlorine in the presence of UV light to give um what see okay nothing else Okay.

[00:07:26]Right.

[00:07:34]Okay.

[00:07:44]Right.

[00:07:52]And this is BHC benzene hexa chloride. Okay. Which is also known as NCO.

[00:08:02]Okay.

[00:08:11]Okay.

[00:08:17]This is the radical. See this is hexag.

[00:08:30]Okay.

[00:08:53]and this is this is reaction propition reaction. Okay. And this is known as hexaclorobenzene.

[00:09:17]Okay. Done.

[00:09:20]The next question is the hydrogenation of unsaturated hydrocarbon using nickel catalyst is known as hydrogenation. Addition of hydrogen, right? addition of H2. Okay.

[00:09:37]H2 in pres that reaction is specifically known as reduction. Okay. And what is LR's catalyst? Lindler's catalyst. This is charcoal PD. Okay.

[00:10:09]AC LG. Okay.

[00:10:14]Birch reduction.

[00:10:16]Okay.

[00:10:18]Question number eight. rule is applicable to the addition of HP2.

[00:10:24]First of all, this carocine and hydrogen addition problem goes to that carbon already.

[00:10:52]Okay. This is known as symmetric.

[00:10:59]Okay.

[00:11:01]First of all, twoin this is the structure of two symmetry of course you can add anywhere both like the double bonds.

[00:11:16]Okay.

[00:11:19]23 butin this is the structure. Okay.

[00:11:30]Okay.

[00:11:33]Propane is an unymmetrical course. Okay. The antimaric of addition of HBO to alan requires the presence of what? Peroxide.

[00:11:48]Okay. Antimar of this is intermediate free radical. Okay. Free radical intermediate.

[00:11:59]See these are all all the concept which are present in NC.

[00:12:05]Okay. Okay. Now question number 10. 10.

[00:12:09]Ounolysis of ethine followed by reduction with zinc and water. Okay.

[00:12:17]followed by reduction with zinc and water.

[00:12:30]Okay. First of all, of course, okay, C plus H.

[00:12:56]And what is this? This is what this is formalihide. Okay. Formal with one carboniz plus H2. Okay. CO2 plus H2.

[00:13:44]alcohol and this is a PQ. This is a PQ6.

[00:13:53]Okay.

[00:13:56]of propane. This is the propane.

[00:14:04]Okay. Oxygen O. Okay. Done.

[00:14:13]CH3 C H O. Okay.

[00:14:17]H C H O. Done. What is this? This is what? What is this? This is my acid alihide. Acid alihide. And what is this?

[00:14:25]formalihide. Okay. Acidihide andhide only.

[00:14:33]Okay.

[00:14:42]Okay.

[00:14:48]Okay.

[00:14:57]First of all, right?

[00:15:21]Okay.

[00:15:26][clears throat] First of all, first of all dilute. Okay.

[00:15:43]Alkaline and not not acidic. Not concentrated, not hot. Okay.

[00:15:51]Okay. Now question number 13. Which of the following gives red brown precipitated with ammonra chloride?

[00:15:58]First of all, ammonrachloride C2 plus NH4. Okay. NH4. Okay.

[00:16:11]property hybridized carbon more electrogative than what sp2 sp2 then sp3 carbon hydrogen is acidic. Okay, this hydrogen is acidic alkine or no seepper and this compound Red.

[00:17:00]Okay.

[00:17:11]Okay. Which hydrocarbon exhibits the highest acidic character? Who?

[00:17:22]SP3 hybridiz is of an hexenine in presence of nhydr3.

[00:17:44]Okay.

[00:17:53]Okay.

[00:17:55]It's a straight chain. 1 2 3 4 5 and six is not position.

[00:18:05]Okay.

[00:18:23]Right.

[00:18:28]Degree of unsaturation is four.

[00:18:41]Okay.

[00:18:44]You want me to draw the structure or what?

[00:18:47]Okay.

[00:19:00]at high temperature last.

[00:19:15]Okay.

[00:19:19]Come to question number okay 17. The thermal decomposition of alkanes is known as word.

[00:19:29]Pure term. Okay. Thermal decomposition of alkans is known as pyrolyis. Not reforming, not isomeization, not aromatization. Okay. Pyrolyis. Okay. Now question number 18. Which confirmation of Ethan is most stable?

[00:19:48]Okay.

[00:19:54]Okay.

[00:20:16]single infinite number of confirmations.

[00:20:29]Okay. Now type of confirmations.

[00:20:42]Okay.

[00:20:55]something right. This is the confirmation is not stable like If this is not stable this one is highly energetic confirmation. Okay. On the other hand, maximum distance and this is this is quite stable. This confirmation is quite stable.

[00:22:09]Okay.

[00:22:17]Okay.

[00:22:18]Uh now then which confirmation of Ethan is most stable.

[00:22:26]Okay.

[00:22:33]Okay.

[00:22:35]Okay. Now, which confirmation of Ethan is least stable? See, right now of course double bond. Okay. Alkan.

[00:22:53]No. No.

[00:22:58]aromatic ring. Okay.

[00:23:03]restricted rotation. Now the dip moment of trans to butin see right and this is the transform of butiny right we all know that is not equal to Second option higher than nois cannot be determined. No, we can't determine equal to one butin. No one's catalyst is chemically. What is Ller's catalyst? See PD Ca3 poison with quinoline.

[00:23:56]Please remember NCO.

[00:24:02]Okay. PD C3 poison with quinoline. Okay.

[00:24:06]Done.

[00:24:15]Okay.

[00:24:19]Right.

[00:24:30]Okay. Now according to an aromatic compound must have 4 N + then only you are a aromatic compound.

[00:24:46]Okay. Now if you have only four n four n electrons no four n electrons then you are antiaromatic okay four n pi electro 2 n electronic nitrating mixture used for the nitration of benzene concentrated HN3 concentrated H24 H2SO4.

[00:25:36]See these are some basic questions.

[00:25:42]Now benzene is carried out using sulfonation addition of HSO3 right.

[00:25:53]Okay H2SO4 H2SO4.

[00:26:05]Okay.

[00:26:10]First of benzinol. Okay. Then this is preparation of benzene. Basically chemical properties of this one nitrating mixture. See with a mixture of concentrated nitric acid and concentrated sulfuric acid. This is known as nitrating mixture.

[00:26:54]acid, right?

[00:26:59]Fuming sulfuric acid. Okay. Like all the questions are derived from NCO3 H. Okay. like HS3 group.

[00:27:20]Okay.

[00:27:21]And C2 H5 C25 C2 H5ation group.

[00:27:33]This is known as group C double bond O CH3. This is known as the group. Okay.

[00:27:44]L3 nothing. These are so very easy.

[00:27:50]Okay. We are done. We are done.

[00:27:57]Okay. Now, which of the following?

[00:28:00]Which of the following is an orthopedirecting?

[00:28:04]OP grouping.

[00:28:08]plus grouping electity.

[00:28:20]On the other hand, this one no basically are minus M group.

[00:29:00]Okay. Comparatively directing. Okay. Now, which of the following is a reacting group?

[00:29:22]CH3 NH2 these are all lone pair okay and nitrogen N O2 it's a minus M groupus M group like for example CH these are all minus M group okay the most stable carboation among the following The tertiary carocetine are the the tertiary carocines are the most stable one. Right? This is tertiary but carboine. This is mythile car.

[00:30:00]This one this is also primary caroc and secondary propile the name itself says. Okay.

[00:30:09]Okay. Now come to question number 30.

[00:30:11]Addition of water to ethine in the presence of H G SO4 and H2SO4 this is nothing but CH triple bond CH this is ethine right H2O in presence of H + 2 N H+ okayh Okay.

[00:30:42]Okay.

[00:30:44]Same reaction.

[00:30:47]Addition of water. What is this ethine in presence of water? H. This is nothing but H2O. In presence of Hgu H+hide okay what NCR derived so we are done with okay important questions.

[00:31:26]Okay, next video. Hello Elen and hello.

[00:31:31]Okay, keep studying. The bait.
