उत्तर
- The reaction shown in the figure is esterification.
- Balanced equation of the reaction between ethanol and ethanoic acid is as follows:
\[\ce{\underset{\text{Ethanol}}{C2H5OH} + \underset{\text{Ethanoic acid}}{CH3COOH} ->[Conc.][H2SO4] \underset{\text{Ethyl ethanoate}}{CH3COOC2H5} + \underset{\text{Water}}{H2O}}\] - The product formed is ethyl ethanoate.
Use: It is used for making fragrances and flavouring agents. - The catalyst used in the reaction is concentrated sulphuric acid.
