Q74 / 180 · AIIMS 2017 · Chemistry

Assertion : Aromatic aldehydes and formaldehyde undergo Cannizzaro reaction. Reason: Aromatic aldehydes are almost as reactive as formaldehyde.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion.
  • B
    If both assertion and reason are true but reason is not the correct explanation of assertion.
  • Correct answer
    C
    If assertion is true but reason is false.
  • D
    If both assertion and reason are false.

Solution

Aromatic aldehydes and formaldehyde do not contain $\alpha$-hydrogen and thus undergo Cannizzaro reaction. Formaldehyde is more reactive than aromatic aldehydes.

Hence, the correct answer is option: 'C'.
