The nitration of aniline in a strong acidic medium results in the formation of m-nitroaniline because:
1. | In spite 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 only m-position |
4. | In an acidic (strong) medium aniline is present as anilinium ion |
