Question

A neutral organic compound X of molecular formula C₂H₆Oon oxidation with alkaline kmno4 gives an acidic compound Y. Compound X reacts with y on warming in the presence of conc. H₂SO₄to give a sweet smelling substance Z. What are X,Y,Z?

Solution

1. Compound X = Ethanol CH3CH2OH
2. Compound Y = Ethanoic acid CH3COOH
3. Compound Z = Ethylethanoate CH3COOC2H5

Neutral compound X is Ethanol, on oxidation with alkaline KMNO4 gives ethanoic acid (Y).

alkaline. KMNO4
CH3CH2OH --------------------> CH3COOH
Ethanol [O] Ethanoic acid
(X) (Y)

Compound Y ethanoic acid reacts with ethanol (X) in the presence of concentrated sulphuric acid (which acts as catalyst) to form the sweet smelling ester, ethyl ethanoate (Z).

CH3COOH + C2H5OH -----------------> CH3COOC2H5
Ethanoic acid Con.H2SO4 Ethylethanoate
(Y) (Z)
