Which one of the following will act as a catalyst in following reaction? H3COOH + CH3CH2OH --> CH3COOC2H5 + H2O
Correct answer: C. H2SO4
- A. NaNO3
- B. Acidified potassium dichromate
- C. H2SO4
- D. SOCl2
Explanation
A catalyst is a substance that speeds up a chemical reaction, or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction. Catalysis is the process of adding a catalyst to facilitate a reaction.For acidic esterification,there is simply need of a compound that can release H+.Esterification is normally carried out in a homogeneous phase in the presence of acid catalysts such as H2SO4, HF, H3PO4, HCl and p-toluene sulfonic acid.

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.
