Q. Which one of the following alkylbromides undergoes most rapid solvolysis in methanol solution to give corresponding methyl ether?
Solution:
Such nucleophilic substitution reactions in which solvent acts as the nucleophile are called solvolysis reactions. Solvolysis of allylic halides occurs by mechanism due to greater stabilization of allyl carbocation intermediates by resonance. -bromo--methylbut--ene react most rapidly by mechanism.
