Question
Explain esterification reaction with the help of a chemical equation. Describe an activity to show esterification.
✓

Answer

Esterification- A process in which an alcohol and a carboxylic acid react in the presence of conc. $H _2 SO _4$ to form an ester. ester.$\text{CH}_3\text{COOH}+\text{C}_2\text{H}_5\xrightarrow{\text{ }\text{Conc.}\text{H}_2\text{SO}}{\text{ }}\text{CH}_3\text{COOC}_2\text{H}_5+\text{H}_2\text{O}$
Activity-
  • Take 1 mL of ethanol mixed with 1 mL of acetic acid along with few drops of conc. H2SO4 in a test tube.
  • Warm it for 5 min. in a water bath.
  • Pour the contents in a beaker containing 20 – 50 mL of water and smell the resulting mixture.
  • It will give a fruity smell indicating the formation of ester.
