[00:07:31]So C R Okay, CH2.

[00:07:52]Okay, done. Now, chemical properties of alcohol. Alcohol alcohol is acidic. Okay.

[00:08:08]Reaction with active metals like metals.

[00:08:10]I mean metals plus metal plus this one.

[00:08:17]Base plus hydrogen, right? RA O N A what is this? This is base plus H2 release coral. Okay. Now R plus NH NH okay N plus H2 release. Oh, these are not so important. So you can skip R O H plus R C O H R C O H this one aloxic acid enough. Okay, now come to reaction with PX3. Um PX3. Okay, I feel like this is a little important. Okay. Uh this one see alcohol in presence of this one PCL3 PCL52 RC. Okay. And this is what this is the method of preparation of that one. Hello alkan. Okay.

[00:09:27]This one this one is a chemical property. No this reaction is a method of preparation preparation of some other chapter. So these are allconing which is a better that one but reagent better reagent for the preparation of this one alky. chloride SO2 plus and this is also known as reagent plus okay these two are gases okay now come to reaction with HX O.

[00:10:34]Okay. RX HB R. Okay.

[00:10:51]Right. Lucas test. See this is a test of alcohol.

[00:25:08]It gives this one nucleophilic addition and this is foruc Okay.

[00:25:33]Nothing but C RC2.

[00:25:36]Okay. RC2 Orim again formalihide formalhide Hihary alcohol form. Okay.

[00:26:03]Now see reaction of react with acetalihide. See acetalihide is not formalihide negative.

[00:26:15]Now okay now this minus will come. This minus will come and attack right.

[00:26:29]Okay. What is this? this with my secondary alcohol. Okay. Now come to my reaction of reassent with acetone followed by hydrayis.

[00:26:40]Check again.

[00:26:47]Okay. This is already group.

[00:26:56]This is tertiary alcohol. Okay. Tertiary alcohol form. See these are the most basic questions. Huh?

[00:27:18]Treatment of water gives NC all of these reactions you will find.

[00:27:26]Okay.

[00:27:29]Phenoline group and 46.

[00:27:45]Okay. Now reaction.

[00:28:01]Now what is this compound?

[00:28:04]Okayhic acid. Okay.

[00:28:14]reaction converts phenol into this related. Okay.

[00:28:26]Okay.

[00:28:36]Cool. Now what is this called? Salicylic acid. Okay. Now aspirine is chemically known as check this is the structure of aspirine aspirine is a medicine.

[00:28:48]Now what is this group called? This is nothing but acetal acetile group. Okay acetile group acid. This will be called estacid salicylic acid. Okay.

[00:29:04]Now come to 18 number. Oxidation of phenol with chromic acid produces this is sodium dromate.

[00:29:14]This same reaction phenol sodium structure for this is known as benzoenon. Okayen.

[00:29:24]Okayen. Now acid is formed by reacting phenol.

[00:29:29]What is acid?

[00:29:33]Which of them is a structure of acid?

[00:29:35]Okay.

[00:29:46]nothing concentrated H and O concentrated H2SO4 okay then now William's ether synthesis is used for the preparation of say Williamson's ether William okay William Okay. Now, William synthesis William synthesis involves the reaction between Okay. R O N A this is sodium. Okay.

[00:30:26]RX this one alkalide. Okay. Alkali reaction alky and sodium aloxxide. Okay.

[00:30:35]Now to prepare tertiary butile methile ether via Williamson synthesis the reactants should be now there's a very good concept a ritation can be anything this group.

[00:31:19]Okay. on the other hand this okay it can only like simple now check to prepare now this is the tertiary butile methile Okay.

[00:31:55]Of course.

[00:32:12]Okay. Okay. This CH3 Br. Okay. Methile bromide. Okay.

[00:32:25]Sodium tertiary oxide and methile bromide. Okay. This one. Okay. This answer is wrong. First of all, answer should be A. Okay. Now cleavage of ethers by concentrated HI favors the formation of check right plus R plus R plus okayh Alcohol alkal iodide. Okay. Alcohol and alcohol and then alkal iodide. Done. Now any salt on heating with H. See again this is nothing. This one O3. Okay. O3 group.

[00:33:30]H+ is a stable it's a stable compound.

[00:33:43]Okay. On the other hand iodide phenile and iodide. Now heating with excentated.

[00:34:01]First of all, right first step out this one. This one excus.

[00:34:27]Okay. Now, denatured alcohol denatured alcohol is ethanol. Okay. Made unfit for drinking by questions. Okay.

[00:34:40]But still denatured alcohol in ethanol made unfit for drinking.

[00:34:47]We cannot consume all the alcohols.

[00:34:50]Okay.

[00:35:00]for drinking.

[00:35:02]It's okay.

[00:35:19]Okay. Absolute alcohol refers to pure ethanol. Remember 100% pure ethanol no mixture nothing mixture only 100% pure ethanol absolute alcohol phenol is more acidic than alcohol right this one no this is known as phoxide ion phoxide That's why this one alcohol this one more check the boiling point of alcohol are much higher than corresponding alan due to why what see yeah they know okay if you Hydrogen bonding like F are the most element.

[00:36:33]Okay. Now hydrogen. Okay. Like for examp now now inter in inter molecular. What is intercol alcohol does to my inter molecular hydrogen bonding? Okay.

[00:37:17]Now the last question which of the following alcohols is most solub soluble soluble soluble in water. Okay. First of all, alcoholic groupy.

[00:37:35]Okay.

[00:37:52]Okay.

[00:37:54]Okay. Then we are done with this chapter like um I hope study hard. Bye-bye.
