Which of the following compounds would undergo `SN_(1)` reaction faster and why ?

Text Solution

Verified by Experts

Compound (B) will give `S_(N)1` reaction faster than compound (A) because `S_(N)1` reaction depends upon the stability of carbocation. Benzyl chloride on lonisation gives `C_(6)H_(5)overset(+)CH_(2)` carbocation which is resonance srabilised while the carbocation obtained from compound (A) is not stabilised by resonance.
