Answer :
c) ester can be produced by reacting alcohol with carboxylic acid
What is esterification ?
The general term for a chemical reaction in which two reactants (usually an alcohol and an acid) combine to create an ester as the end product is "esterification." Esters are frequently found in organic chemistry and biological materials, and they frequently have a distinctive, fruity scent.
The process of making ester typically involves combining a carboxylic acid with an excess of an alcohol while using a tiny amount of a strong acid, like conc.H2SO4, as a catalyst. The esterification reaction is reversible, and the equilibrium constant for the reaction is often close to 1. Numerous strategies are employed to raise the ester yield because the reaction is reversible.
