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?
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 (CH3−COOH).
CH3−CH2−OH+2[O]KMnO4−−−−−→CH3−COOH+H2O.
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).
