Vedclass · Answer

(C) Aryl halides are generally less reactive towards nucleophilic substitution reactions.However,the presence of an electron-withdrawing group $(-NO_2)$ at the ortho- or para-position significantly increases the reactivity of haloarenes towards nucleophilic substitution due to the stabilization of the carbanion intermediate.In $I$ ($o$-nitrofluorobenzene),the $-NO_2$ group is at the ortho-position.In $III$ ($p$-nitrofluorobenzene),the $-NO_2$ group is at the para-position.In $II$ ($m$-nitrofluorobenzene),the $-NO_2$ group is at the meta-position,where it does not stabilize the intermediate carbanion through resonance as effectively as it does at the ortho- and para-positions.Thus,the reactivity order is $I > III > II$.

The rate of reaction of $NaOH$ with the following compounds follows the order:
$I$: $1$-fluoro-$2$-nitrobenzene
$II$: $1$-fluoro-$3$-nitrobenzene
$III$: $1$-fluoro-$4$-nitrobenzene
