Which of the following alcohol can give a lodoform reaction?
Correct answer: D. Ethanol
- A. Methanol
- B. 1-Butanol
- C. 1-Propanol
- D. Ethanol
Explanation
The iodoform reaction occurs with compounds that have a methyl group attached to a carbon bearing a hydroxyl group (-OH) or a carbonyl group (-C=O). Ethanol (CH₃CH₂OH) meets this requirement because it can be oxidized to acetaldehyde (CH₃CHO), which has the necessary structure for the iodoform reaction.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
