$B$ reacts faster than $A$

Vedclass · Answer

(B) The rate of $S_N1$ reaction depends on the stability of the carbocation intermediate formed after the departure of the leaving group $(Br^-)$.For compound $(A)$,the carbocation formed is a cyclopentadienyl cation,which has $4\pi$ electrons and is anti-aromatic,making it highly unstable.For compound $(B)$,the carbocation formed is a pyrylium cation,which has $6\pi$ electrons ($4$ from double bonds and $2$ from the lone pair on oxygen) and is aromatic,making it highly stable.Since the stability of the carbocation intermediate is directly proportional to the rate of $S_N1$ reaction,compound $(B)$ reacts much faster than compound $(A)$.

Which of the following statements is correct regarding the rate of hydrolysis of the compounds $(A)$ and $(B)$ by $S_N1$ reaction?
