Q. If meta-nitroaniline is chlorinated, the major product is:

Amines

Solution:

$- NH _{2}$ group increases $e ^{-}$ density at $0-\& p$ - positions $\&- NO _{2}$ position.

$\because$ Chlorination is electrophilic substitution reaction, position of attack in directed by $- NH _{2}$ group. So, $Cl$ will be attached to $o- $ or $p-$ position of $- NH _{2}$ group.

In option $ (a) \& (c) -I $ effect of $- NO _{2}$ group is more pronounced at $o- $ position wrt $- NO _{2}$ group than at pposition which decreases $e ^{-}$ density.

$\therefore (a) $ is correct.
