Question

Amino group is o, p-directing for electrophilic substitution reaction. But, on nitration the major product is m-nitroaniline because (A) aniline gets protonated with strong acids to give anilinium ion which is m-directing (B) nitration requires nitric acid which oxidises - NH2 to -NO2 group (C) electrophile NO2+ is a m-directing group (D) benzene ring exerts + I effect and deactivates the ring

Tardigrade Admin · Accepted Answer

Correct answer is (a) aniline gets protonated with strong acids to give anilinium ion which is m-directing

Q. Amino group is $o$ , $p$ -directing for electrophilic substitution reaction. But, on nitration the major product is $m$ -nitroaniline because

aniline gets protonated with strong acids to give anilinium ion which is $m$ -directing

nitration requires nitric acid which oxidises $- N H_{2}$ to $- N O_{2}$ group

electrophile $N O_{2}^{+}$ is a $m$ -directing group

benzene ring exerts $+ I$ effect and deactivates the ring

Correct answer is (a) aniline gets protonated with strong acids to give anilinium ion which is $m$ -directing

Q. Amino group is o, p-directing for electrophilic substitution reaction. But, on nitration the major product is m-nitroaniline because

aniline gets protonated with strong acids to give anilinium ion which is m-directing

nitration requires nitric acid which oxidises −NH2​ to −NO2​ group

electrophile NO2+​ is a m-directing group

benzene ring exerts +I effect and deactivates the ring
