Acetaldehyde undergoes the iodoform reaction, whereas benzyl aldehyde does not because it lacks a methyl group.

1. Acetaldehyde reacts positively in the iodoform test.
2. Benzyl aldehyde does not produce iodoform.
3. The iodoform test is characteristic of compounds with a methyl ketone group.
4. All of the statements are incorrect.

Correct answer: Acetaldehyde reacts positively in the iodoform test.

Solution

CH3CHO (acetaldehyde) gives the Iodoform test because it contains a methyl group directly attached to the carbonyl carbon, which is a requirement for the test.
