  Which of the following compounds would undergo  reaction faster and why ?

Answer:

   In  reactions, carbocations are the intermediates. Obviously more stable the carbocation, more reactive is the alkyl halide. Since allyl chloride upon ionization gives allyl cation which is stabilized by resonance but the carbocation obtained from n-propyi chloride is not, therefore, allyl chloride undergoes hydrolysis much faster than n-propyl chloride.
