Question:
Which of the following aldehydes will undergo Cannizzaro reaction?
Which of the following aldehydes will undergo Cannizzaro reaction?
Show Hint
Cannizzaro reaction occurs in aldehydes without alpha-hydrogens and involves a disproportionation reaction.
Updated On: Jul 11, 2025
- CH3 - CHO
- (CH3)3CCHO
- CH3 - CH2 - CHO
- CH3 - CH2 - CH2CHO

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Cannizzaro reaction occurs when aldehydes without alpha-hydrogens (like formaldehyde and certain other aldehydes) undergo a base-catalyzed disproportionation reaction. In this case, the only aldehyde that will undergo the Cannizzaro reaction is acetone (CH3)3CCHO. Other aldehydes listed have alpha-hydrogens and will undergo aldol reactions instead.
