The transfer of hydride ion to carbonyl group

Vedclass · Answer

(B) The mechanism of the Cannizzaro reaction involves the following steps: $1$. Nucleophilic attack of $\stackrel{\ominus}{O}H$ on the carbonyl carbon of one molecule of benzaldehyde to form a dihydroxyalkoxide intermediate. $2$. The hydride ion $(H^{\ominus})$ transfer from the dihydroxyalkoxide intermediate to the carbonyl carbon of another molecule of benzaldehyde. This is the rate-determining step (slowest step) because it involves the breaking of a $C-H$ bond. $3$. Rapid proton exchange between the resulting carboxylic acid and the alkoxide ion to form the carboxylate ion and alcohol.
