The correct sequence of steps involved in the mechanism of Cannizaro's reaction is
Options
- Anucleophilic attack, transfer of H ⁻ and transfer of H ⁺
- Btransfer of H ⁻ , transfer of H ⁺ and nucleophilic attack
- Ctransfer if H ⁺ , nucleophilic attack and transfer of H ⁻
- Delectrophilic attack by OH ⁻ , transfer of H ⁺ and transfer of H ⁻
Correct answer
A. nucleophilic attack, transfer of H ⁻ and transfer of H ⁺
Step-by-step solution
The Cannizaro reaction is as The mechanism of Cannizaro reaction is as Step Ist : Attack of nucleophile OH ⁻ to the carbonyl carbon Step IInd : The transfer of hydride ion from anion (I) to second molecule of aldehyde and finally rapid transfer of proton takes place.
