An organic compound ‘X’ is a liquid at room temperature. It is also a very good solvent and has the molecular formula C₂ H₆ O. on oxidation ‘X’ gives ‘Y’ which give, break effervescence on reacting with NaHCO₆. X reacts with Y in the presence of conc.H₂SO₂ to give another compound ‘Z’ which has a pleasant smell. Identify X, Y and Z. also write chemical equations to show the formation of Y and Z.
