an organic Compound A is liquid in room temperature. it is also a good solvent and has the molecular formula C2H6O. A on oxidation gives a compound B which gives effervescence with sodium bicarbonate. A reacts with B in tye presence of sulphuric acid to give another compound C which has a pleasant smell. identify A, B and C and write the chemical equations for the reactions involved in the formation of B and C

Solution

Compound A C₂H₆O is ethanol.
Ethanol on oxidation gives compound B, which gives effervescence with sodium hydrogen carbonate. This implies it is corresponding carboxylic acid that is ethanoic acid or acetic acid.
reaction:
C₂H₅OH $\overset{O x i d a t i o n}{\to}$ CH₃COOH
Now ethanoic acid reacts with ethanol in presence of conc.H₂SO₄ to yield C, which has pleasant smell. This implies formation of ester that is ethyl acetate.
reaction:
C₂H₅OH + CH3COOH $\overset{{Conc.H}_{2} {SO}_{4}}{\to}$ CH₃COOC₂H₅
