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

Haloarenes are less reactive than haloalkanes and haloalkenes. Explain.
Assertion: Chlorobenzene is resistant to nucleophilic substitution reaction at room temperature.
Reason (R): C–Cl bond gets weaker due, to resonance.
