In the Cannizzaro reaction given below:
`2Ph-CHO overset(overset(Θ)OH)rarrPh-CH_(2)OH+PhCO_(2)^(-)` 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.
