Question
What is the Rate Determining Step (RDS) in the standard Cannizzaro reaction mechanism for aldehydes lacking $\alpha$ -hydrogens?
Answer: B
💡 Solution & Explanation
The direct transfer of the hydride ion ($H^-$) from the highly energetic intermediate to the neutral carbonyl carbon of the second molecule is kinetically slow and acts as the RDS.
