Allyl Chloride, CH₂=CH—CH₂Cl, is more readily hydrolysed than n-propyl chloride, CH₃—CH₂—CH₂Cl, because of the presence of the ϖ bond which gives the property of resonance stabilization to the CH₃—CH₂—CH₂⁺ carbocation to be very stable. Due to the formation of carbocation, the molecule undergoes hydrolysis more readily.
