NEET 2018 Chemistry question

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

(1)In absence of substituents nitro group always goes to m-position.
(2)In electrophilic substitution reactions amino group is meta directive.
(3)Inspite of substituents nitro group always goes to only m-position.
(4)In acidic (strong) medium aniline is present as anilinium ion.Correct

Answer: (4)

Solution

The nitrating mixture () is strongly acidic, so aniline is largely protonated to the anilinium ion, . The group is strongly electron-withdrawing and is meta-directing, so substantial m-nitroaniline (about 47%)
