Question

A neutral organic compound X of molecular formula C2H6O on oxidation with acidified potassium dichromate gives an acidic compound Y. Compound X reacts with Y on warming in the presence of conc. H2SO4 to give a sweet smelling substance Z. What are X, Y and Z?

Solution

The neutral organic compound 'X' having the molecular formula C2H5OH is ethanol (alcohol with functional group -OH).
When ethanol undergoes oxidation reaction (controlled combustion) with acidified potassium dichromate, it gets oxidised to form an acidic compound, Y, called ethanoic acid (CH3COOH).
Ethanol reacts with ethanoic acid in the presence of concentrated sulphuric acid to release a sweet smelling ester, Z, called ethyl ethanoate (CH3-COO-CH2-CH3).

The chemical equations involving the compounds are as follows:
CH3CH2OH + 2[O] → CH3COOH + H2O.
CH3COOH + CH3CH2OH→ CH3COOC2H5 + H2O
