Solution
The correct option is
B
the transfer of hydride to the carbonyl group
The mechanism of the Cannizzaro reaction involves 3 steps.
The first step is the addition of hydroxide ion to the carbonyl group. It is a reversible reaction.
The second step is the transfer of hydride ion from hydroxy alkoxide to another aldehyde molecule. It is slowest step.
The third step is the exchange of protons between the acid and alkoxide ion.
