Distinguish between estercation and saponication reaction with the help of the chemical equations for each.State one use of each (i) esters, and (ii) saponication process.
Answers
Esterfication reaction: when an organic acid reacts with an alcohol in the presence of acid catalyst, it produces a sweet smelling substance called ester. this reaction is called esterfication reaction, e.g.,
CH3COOH + C2H50H ---------> CH3COOC2H5 +H2O
Saponification: ester reacts in the presence of an acid or a base to give back the alcohol and the carboxylic acid. this reaction is known as saponification because it is used in the preparation of soap.
CH3COOC2H5 -----------> CH3COOH + C2H5OH
Use of esters:
Esters are used in synthetic flavours, perfumes, cosmetics, lacquers, paints and varnishes.
Use of saponification reaction:
It is used in the preparation of soaps on a commercial basis.
