Question

Nitration of aniline in strong acidic medium also gives m-nitroaniline because

• A. In absence of substituents nitro group always goes to m-position.
• B. In electrophilic substitution reactions amino group is meta directive.
• C. Inspite of substituents nitro group always goes to only m-position.
• D. In acidic (strong) medium aniline is present as anilinium ion.

Answer 1

Answer: (D)

As $-\overset{\oplus \, }{N H_{3}}$ is m-directing and strongly ring deactivating, hence besides para (51%) and ortho (2%), meta product (47%) is also formed in significant yield here.
