In the Cannizzaro reaction given below 2 C ₆ H ₅ CHO OH ⁻ C ₆ H ₅ CH ₂ OH + C ₆ H ₅ COO ⁻ The slowest step is

Options

  1. AThe attack of OH ⁻ at the carbonyl group
  2. BThe transfer of hydride ion to the carbonyl aroun
  3. CThe abstraction of proton from the carboxylic acid
  4. DThe deprotonation of benzyl alcohol

Correct answer

B. The transfer of hydride ion to the carbonyl aroun

Step-by-step solution

H ⁻ is obtained by fission of C - H bond of ( B ) . It is transferred to (II). This is the slowest step.
