The presence of nitro group (-NO2)at O/P positions increases the reactivity of haloarenes towards nucleophilic substitution reactions.

Question

Give reasons :

The presence of nitro group (-NO₂)at O/P positions increases the reactivity of haloarenes towards nucleophilic substitution reactions.

Answer 1

-NO₂ acts as Electron withdrawing group or -l effect.

Detailed Answer:

In haloarenes, NO₂ group is present at O/P position results in the stabilisation of resulting carbanion by-R and - I effects and therefore increases the reactivity of haloarenes towards nucleophilic substitution reactions.
