Assertion : Aromatic aldehydes and formaldehyde undergo Cannizzaro rea

1.	Assertion : Aromatic aldehydes and formaldehyde undergo Cannizzaro reaction Reason : Aromatic aldehydes are almost as reactive as formaldehyde.A. If both assertion and reason are correct and reason is correct explanation for assertion.B. If both assertion and reason are correct and reason is not correct explanation for assertion.C. If assertion is correct but reason is incorrect.D. If assertion as well as reason are both incorrect.
Answer» Correct Answer - C Correct reason. Both aromatic aldehydes and formaldehyde donot have `alpha`-hydrogen and participtate in Cannizzaro reaction. However, aromatic aldehydes are less reactive than formalhyde.
