A compund has the following properties: It is a liquid at room temperature and atmospheric pressure It does not mix properly with water It does not decolourize acidified potassium manganate(VII) What could X be?
Correct answer: D. Ethyl ethanoate
- A. Ethane
- B. Ethanoic acid
- C. Ethanol
- D. Ethyl ethanoate
Explanation
Option A is gas. Options B and C are totally miscible in H20 (through hydrogen bonding with H20). The correct option is D as rest all are incorrect and do not match with the given statements.This is an ester and at room temperature it is in Liquid state also it is not completely soluble in water and does not react with Potassium Maganete(VII).

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.
