The correct order of reactivity of following haloarenes towards nucleophilic substitution with aqueous NaOH is: Choose the correct answer from the options given below:

Step-by-step solution

The intermediate formed in aromatic nucleophilic substitution reaction is carbanion. Carbanion stabilised by electron withdrawing groups. Aryl halides are less reactive towards nucleophilic aromatic substitution with aqueous NaOH . Introduction of electron releasing group like OCH 3 group further decreases its reactivity towards nucleophilic substitution. But the introduction of electron withdrawing groups like NO 2 group particularly at the ortho and para position increases its reactivity towards nucleophilic subs
