In Cannizzaro reaction given below :
` 2PhCHO overset(: OH^(-)) to PhCH_(2)OH + PhCOO^(-)` the slowest step is

A

the attack of `OH^(-)` at the carbonyl group

B

the transfer of hydride to the carbonyl group

C

the abstraction of proton from carboxylic acid

D

the deprotonation of Ph - COOH

Text Solution

Verified by Experts

The transfer of hydride ion to the carbonyl group is the slowest or the rat determiningg step.

Hence, (B) is the correct answer.
