In the following reaction the reason why meta-nitro product also formed is :
In the following reaction the reason why meta-nitro product also formed is :
Show Hint
To obtain only ortho/para products from aniline, you must first "protect" the amino group by acetylation (forming acetanilide) before nitration.

- $-NH_2$ group is highly meta-directive
- $-NO_2$ substitution always takes place at meta-position
- Formation of anilinium ion
- low temperature

The Correct Option is C
Solution and Explanation
Step 1: Nitration uses a mixture of conc. $H_2SO_4$ and conc. $HNO_3$.
Step 2: In this strongly acidic medium, the basic aniline ($Ph-NH_2$) gets protonated to form the anilinium ion ($Ph-NH_3^+$).
Step 3: The $-NH_3^+$ group is electron-withdrawing and strongly meta-directing.
Step 4: This leads to the formation of nearly 47% meta-nitroaniline.
