The nitration of aniline in a strong acidic medium results in the formation of m-nitroaniline because:
| 1. | In spite of substituents, the nitro group always goes to only the m-position. |
| 2. | In electrophilic substitution reactions, the amino group is meta-directive. |
| 3. | In the absence of substituents, the nitro group always goes to only m-position. |
| 4. | In an acidic (strong) medium, aniline is present as an anilinium ion. |
