Question

Define saponification and esterification with chemical equation​

Answer 1

HEYA MATE !!

ESTERIFICATION:Esterification is the reaction in which a Carboxylic acid combines with an alcohol in the presence of little concentrated sulphuric acid to form an ester.

SAPONIFICATION:On treating with sodium hydroxide,the ester is converted back to alcohol and sodium salt of carboxylic acid.This reaction is known as saponification reaction bcoz it helps in the formation of soaps.

hope it helps

pls mark it as the brainliest answer :)

GOOD LUCK FOR UR BOARD EXAMS !!

Answer 2

          SAPONIFICATION                                                  ESTERIFICATION

                                                                   

1) When an ester is reacted with                         1)When an alochol is reacted

 an acid or base , it gives back the                      with a carboxylic acid , it

  corresponding carboxylic acid and                   forms an ester in the

  alcohol its called a saponification                      presence of excess of

reaction.                                                                  conc. sulphuric acid , it is

                                                                                called an esterification  

                                                                                reaction.

2. In a Saponification reaction there is               2)In an esterification reaction

   no need of a catalyst.                                          catalysts are used.                          

Eg. CH3COOC2H5 + NaOH                                Eg. CH3COOH + C2H5OH        

→ C2H5OH + CH3COONa                                          → CH3COOC2H5 + H2O                                

3. Used in preparation of soaps                         3. Used in making perfumes

                                                                                 and the like.
