Carbon & its Compounds (C10)

Distinguish between esterification and saponification reactions with the help of the chemical equations for each. State one use of each (i) esters, and (ii) saponification process.

Esterification: A process in which an alcohol and a carboxylic acid react in the presence of conc. H2SO4 to form an ester.

CH3COOH + C2H5OH → CH3COOC2H5 + H2O

Saponification: A process in which an ester reacts with sodium hydroxide to form sodium salt of an acid and alcohol. An ester reacts in the presence of an acid or a base to give back the alcohol and carboxylic acid.

CH3COOC2H5 + NaOH → C2H5OH + CH3COONa

Esters are used in ice creams and perfumes. Saponification process is used in preparation of soap.
