प्रश्न
Raina while doing certain reactions observed that heating of substance ‘X’ with a vinegar-like smell with a substance ‘Y’ (which is used as an industrial solvent.) in the presence of conc. Sulphuric acid in a water bath gives a sweet-smelling liquid ‘Z’ having molecular formula C4H8O2. When heated with caustic soda (NaOH), ‘Z’ gives back the sodium salt and the compound ‘Y’.
Identify ‘X’, ‘Y’, and ‘Z’. Illustrate the changes with the help of suitable chemical equations.

उत्तर
- X - Ethanoic acid/acetic acid/CH3COOH
- Y - Ethanol/Ethyl alcohol/C2H5OH
- Z - Ethyl ethanoate/Ester/CH3COOC2H5
\[\ce{\underset{(Ethanoic acid)}{CH3-COOH} + \underset{(Ethanol)}{CH3 - CH2OH} <=>[Acid]\underset{(Ester)}{CH3-\underset{\overset{11}{O}}{C}-O-CH2-CH3} + H2O}\]
\[\ce{CH3COOC2H5 ->[NaOH]C2H5OH + CH3COONa}\]
