In the following reaction, the reason why meta-nitro product also formed is:
Options
- AFormation of anilinium ion
- B group is highly meta-directive
- C substitution always takes place at meta-position
- Dlow temperature
Correct answer
A. Formation of anilinium ion
Step-by-step solution
Aniline on protonation gives anilinium ion which is meta directing. So considerable amount of meta product is formed.
Direct nitration of aniline yields tarry oxidation products in addition to the nitro derivatives. Moreover, in the strongly acidic medium, aniline is protonated to form the anilinium ion which is meta directing. That is why besides the ortho and para derivatives, significant amount of meta derivative is also formed.
