Question

Which of the following statement is correct regarding the rate of hydrolysis of the compounds $\left(A\right)$ and $\left(B\right)$ by $S_{N^1}$ reaction ?

• A. $A$ reacts faster than $B$
• B. $B$ reacts faster than $A$
• C. Both $A$ and $B$ react at the same rate
• D. Neither $A$ nor $b$ reacts

Answer 1

Answer: (B)

$B$ reacts faster than $A$

The formation of cation is readily favorable in 'b' due to presence of oxygen. The carbocation formed will be resonance stabilized by lone pair electrons of oxygen as given below.
