Question:
Which of the following will not give iodoform test ?
Which of the following will not give iodoform test ?
Updated On: Jul 7, 2022
- Ethanol
- Ethanal
- Isopropyl alcohol
- Benzyl alcohol
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Any group having $CH_3CO$- group, along with ethanol and isopropyl alcohol would give iodoform test positive. This is because ethanol under reaction condition (oxidising) produces ethanal having $CH_3CO-$ group. Also any secondary alcohol having $CH_3-C-(OH)-$ group also produces a ketone having $CH_3CO^-$ group on oxidation

Alcohols, Phenols, and Ethers
Alcohol is formed when a saturated carbon atom bonds to a hydroxyl (-OH) group. It is an organic compound that contains a hydroxyl functional group attached to a carbon atom.
Phenol is formed when the -OH group replaces the hydrogen atom in benzene. It is an organic compound in which a hydroxyl group directly attaches to an aromatic hydrocarbon.
Ether is formed when oxygen atom bonds to two alkyl or aryl groups. It is an organic compound that has an oxygen atom that is connected to two aryl and alkyl groups.
