Question

Allyl chloride is hydrolysed more readily than n-propyl chloride. Why?

Short/Brief Note
Advertisements

Solution

Allyl chloride shows high reactivity because the carbocation formed by hydrolysis is stabilised by resonance while no such stabilisation of carbocation exists in the case of n-propyl chloride.
