उत्तर
| Esterification | Saponification |
| 1. It is a reaction in which carboxylic acids react with alcohols in the presence of conc. H2SO4 | It is a reaction in which an ester reacts with an alkali. |
| 2. The formation of a fruity smell compound takes place called an ester. | The formation of soap takes place. |
| 3. It needs a catalyst for a reaction to occur. | No catalyst is required for the reaction to take place. |
|
4. The chemical equation involved is: \[\ce{CH3COOH + C2H5OH ->[conc. H2SO4]CH3COOC2H5 + H2O}\] |
The chemical equation involved is: \[\ce{CH3COOC2H5 + NaOH -> CH3COONa + C2H5OH}\] |
