Question

Toluene is o/p orienting with respect to an electrophilic substitution reaction due to ?

• A. I effect of the methyle group
• B. I as well as
  + M effect of the methyl group
• C. hyperconjugation between the methyl group and the phenyl ring
• D. +M effect to the methyl group.

Answer 1

The correct option is B I as well as

+ M effect of the methyl group
solution:

In Toluene, the methyl group releases electrons towards the benzene ring partly due to inductive effect and mainly due to hyperconjugation. Thus the reactivity of the ring towards electrophilic substitution increases and the substitution is directed at ortho and para positions to the methyl group.

Toluene o/p orienting with respect to an electrophilic substitution reaction due to. +M effect to the methyl group.

hence the correct option:B
