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 the carboxylic acid.

D

the deprotonation of `Ph CH_(2) OH`.

Text Solution

Verified by Experts

The correct Answer is:
B
The possible mechanism is
The showest stop is the transfer of hydride to the carbonyl ground as shown in stop (ii).
