please explain this why p-methoxybenzyl bromide reacts faster than p-nitrobenzyl bromide with ethanol to form ether?
Asked by vinodjoshi112233 | 29th Sep, 2017, 07:29: AM
Methoxy group is an electron releasing group which stabilises the intermediate carbocation.
Nitro group is an electron withdrawing group which destabilises the intermediate carbocation.
Formation of carbocation is the rate determining step, more the stability of carbocation, faster is the reaction.
Hence, p-methoxybenzyl bromide reacts faster than p-nitrobenzyl bromide with ethanol to form ether.
