Solution


Q.

Nitration of aniline in strong acidic medium also gives m-nitroaniline because            [2018]
1 inspite of substituents nitro group always goes to only m-position  
2 in electrophilic substitution reactions amino group is meta directive  
3 in absence of substituents nitro group always goes to m-position  
4 in acidic (strong) medium aniline is present as anilinium ion.  

Ans.

(4)

The reason for formation of an unexpected amount of m-nitroaniline is that under strongly acidic condition of nitration, most of the aniline is converted into anilinium ion and since, –N+H3 is a m-directing group, therefore, a large amount of m-nitroaniline is also obtained.
