00:01
Let me draw the first reactant.
00:03
We have here a benzene ring and on this benzene ring we have a tertiary butile group attached.
00:12
So this is tertiary butile benzene.
00:15
Then we have given reagent hno3 that is one equivalent and we have concentrated h2 so4.
00:32
Whenever these reagents are given reagents are given whenever nitric acid is given in presence of concentrated sulfuric acid this leads to nitration so nitration will take place here now what will be the final product so in nitration generally the no2 group nitro group that substitutes at metaposition but in this case this tertiary butile group that is a strong electron releasing group and it will generate the electron density at ortho and parapolitions and the stable product that is one with paraposition so the final product will be so and no to group substituted at paraposition that is the major product okay moving on to next second part we have benzene ring this time we have given this as this is here alkyl chloride okay one equivalent and alcl3 this alcl 3 is a levis base in presence of alcl 3 whenever alkyl chloride is given this leads to fridyl craft alkylation okay so the reaction here is fridyl crafts let me write it again.
02:32
Fredelcraft alkylation.
02:38
Now, so we have this benzene ring and this one, two, three.
02:52
So, profile group will be substituted here.
02:54
One, two, three.
02:56
So this is propile benzene here.
02:59
That is the major product.
03:01
Okay? moving on to next.
03:03
Third part, this time we have a nitrogen atom containing algal group, this further attached to this benzene ring.
03:21
Then this nitrogen atom is further attached to carbonyl carbon and that is further attached to another benzene ring.
03:33
Now we have given bromine one equivalent of bromine.
03:39
In presence of fcbr3.
03:43
These reagents are used for bromination.
03:49
So substitution reaction will take place.
03:53
Bromination will take place here.
03:59
Now the question is at which wing.
04:02
So here this nitrogen, this nitrogen has a pair of electron.
04:08
This is electron rich.
04:10
Being electron rich, it can increase the electron density at otho and paraposition.
04:16
The major product is one with paraposition.
04:20
So the product will be the benzine ring, nitrogen atom, alkyl group, carboneal carbon, benzine ring.
04:37
This benzine ring will remain as such and gromogro -group will be substituted at paraposition.
04:45
That is the major product.
04:47
Moving on to next...
