CH3COOH + CH3CH2OH ⇌ CH3COOC2H5 + H2O Which one of the following will act as a catalyst in the above reaction?
Correct answer: B. H2SO4
- A. HNO3
- B. H2SO4
- C. Acidified potassium dichromate
- D. SOCl2
Explanation
In this reaction, Ester is being formed. Esters are produced when carboxylic acids are heated with alcohols in the presence of an acid catalyst. The catalyst is usually concentrated sulfuric acid. Dry hydrogen chloride gas is used in some cases, but these tend to involve aromatic esters.

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.
