Options

Correct Answer
D Propanone
Correct Answer

Option C is the correct answer.

Detailed Explanation

Methanol (CH3OH) does not give a positive iodoform test because it does not have the CH3-CO- or CH3-CH(OH)- group. Ethanol, ethanal, and propanone all give positive iodoform tests.

Hint

Which alcohol lacks the CH3-CHOH- group?
