MCQ
Rate of reaction is maximum if $G$ is
  • A
    $-OCH_3$
  • B
    $-CH_3$
  • $-NO_2$
  • D
    $-H$

Answer

Correct option: C.
$-NO_2$
c
The given reaction is a nucleophilic substitution reaction. This will be more favored is the electron density of the ring is reduced by some electron withdrawing group. Hence, the rate of given reaction is maximum if $G$ is $NO _2$.
