Assertion (A) Toluene on Friedal Crafts ...

Assertion (A) Toluene on Friedal Crafts methylation gives o - and p-xylene.
Reason ( R) `CH_(3)`-group bonded to benzene ring increases density at o - and p- position.

A

Both A and B are correct and R is the correct explanation of A

B

Both A and R are not correct

C

Both A and R are not correct

D

A is not correct but R is correct

Text Solution

Verified by Experts

The correct Answer is:
a
Both assertion and reason are correct and reason is the correct explanation of assetion.
Toluene has - `CH_(3)` group attached to benzene - `CH_(3)` group activates the benzene ring for the attack of an electrophile .
In resonating structure of toluene electronic density is more on orthe and pata position . Hence , substitution takes place mainly at these positions.
