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 `:overset(Theta)(OH)` at the carboxyl group

B

The transfer of hydride to the carbonyl group

C

The abstraction of proton from the carboxylic group

D

The deprotonation of `Ph CH_(2)OH`

Text Solution

Verified by Experts

The correct Answer is:
B
`Ph-overset(O)overset(||)(C )-H+overset(Theta)(O)H`

`overset(H)underset("exchange")rarr Ph-overset(O)overset(||)(C )-overset(Theta)(O)-Ph-CH_(2)-OH`.
