Solution

Correct Answer:

Propanone

Iodoform test is given by compounds containing the CH3CO- group (methyl ketones) or alcohols oxidizable to it. Propanone has the CH3CO- functional unit and forms yellow CHI3 precipitate with I2/NaOH. The other listed aldehydes do not satisfy this structural requirement.

This easy difficulty chemistry question is from the chapter organic compounds containing oxygen, covering the topic of carbonyl compounds. It appeared in the 2025 exam.
