What substance is formed by reaction of ethanol and ethanoic acid in presence of concentrated sulphuric acid?

Answer and explanation

Correct answer: Ester

Ethanol is an alcohol and ethanoic acid is a carboxylic acid. They react in the presence of concentrated sulphuric acid to produce an ester and water; specifically, ethyl ethanoate is formed: CH3COOH + C2H5OH ⇌ CH3COOC2H5 + H2O. This is esterification, so option A is correct. Carbonate, base, and graphite are not products of this reaction.
