Question:
Which of the following statements is not true for acetaldehyde?
Which of the following statements is not true for acetaldehyde?
Show Hint
$\alpha$-H present → no Cannizzaro reaction.
Updated On: Apr 23, 2026
- It will undergo an aldol condensation reaction.
- It will undergo a Cannizzaro reaction.
- It will undergo a haloform reaction.
- Enolisation is catalysed by acid or base
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Cannizzaro reaction occurs only in aldehydes without $\alpha$-hydrogen.
Step 1: Acetaldehyde (CH$_3$CHO) has $\alpha$-hydrogen.
Step 2: Hence it undergoes aldol condensation and haloform reaction.
Step 3: Cannizzaro reaction does NOT occur.
Conclusion:
Incorrect statement = (B)
