A compound has the properties below:it is a liquid at room temperature,it is immiscible with water,it does not decolourise acidified potassium manganate(VII).What could it be?
Correct answer: D. Ethyl ethanoate
- A. Ethane
- B. Ethanoic acid
- C. Ethanol
- D. Ethyl ethanoate
Explanation
Ethyl ethanoate is an ester, which is a liquid at room temperature and is not readily soluble in water. Unlike alcohols or aldehydes, esters are resistant to oxidation by KMnO4. Ethane is a gas, while ethanoic acid and ethanol are both miscible with water.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
