Question:medium
Which compound does not show an iodoform test?
Which compound does not show an iodoform test?
Show Hint
Check which compound lacks a methyl group directly attached to a carbonyl.
Updated On: Jul 3, 2026
- Acetaldehyde
- Acetone
- Propanal
- Acetophenone
Show Solution
The Correct Option is C
Solution and Explanation
Method: mechanism check. The iodoform reaction needs a methyl group directly bonded to carbonyl carbon to form the CI3 leaving group. Propanal's alpha hydrogens belong to a CH2 group, not CH3, so the trihalomethyl leaving group can never form.
