Tertiary alcohols produce_with acidified KMnO4
Correct answer: D. No reaction
- A. Ketones
- B. Malonic acid
- C. Aldehydes
- D. No reaction
Explanation
Tertiary alcohols do not undergo oxidation with acidified potassium permanganate (KMnO4) because they lack a hydrogen atom on the carbon atom attached to the hydroxyl group, which is essential for the oxidation process. Therefore, there is no reaction. In contrast, aldehydes and ketones can be oxidized by KMnO4 under appropriate conditions, but tertiary alcohols are resistant to this kind of oxidation. The other options are incorrect because they involve products that cannot be derived from a tertiary alcohol through this 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.
