Question
Nitration of aniline in strong acidic medium also gives m-nitroaniline because
Inspite of substituents nitro group always goes to only m-position.
In electrophilic substitution reactions amino group is meta directive.
In acidic (strong) medium aniline is present as anilinium ion.
In absence of substituents nitro group always goes to m-position.
Solution
C.
In acidic (strong) medium aniline is present as anilinium ion.
In acidic medium, aniline is protonated to form anilinium ion which is meta-directing.
Hence besides para (51%) and ortho (2%), meta product (47%) is also formed in significant yield.
