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. in spite of substituents nitro group always goes to only m-position
D. in acidic (strong) medium aniline is present as anilinium ion

Answer 1

Correct Answer - D
In strongly acidic medium, aniline is protonated to form the anilinium ion.

Since, anilinium ion so formed is meta directing, thus besides ortho and para derivatives, significant amount of meta derivative is also formed.
