प्रश्न
Shristi heated Ethanol with a compound A in presence of a few drops of concentrated sulphuric acid and observed a sweet smelling compound B is formed. When B is treated with sodium hydroxide it gives back Ethanol and a compound C.
- Identify A and C
- Give one use each of compounds A and B.
- Write the chemical reactions involved and name the reactions.
उत्तर
- A - Ethanoic acid/ Or any other carboxylic acid,
C - Sodium salt of ethanoic acid/any other carboxylic acid/sodium ethanoate. - Use of A - dil solution used as vinegar in cooking/preservative in pickles.
Use of B - making perfumes, flavoring agent. - \[\ce{CH3COOH + C2H5OH ->[Conc H2SO4] CH3COOC2H5 + H2O}\]
