. An organic compound X on heating with cone. H 2S04 forms a compound Y
which on addition of one molecule of hydrogen in the presence of nickel forms a compound 'Z'. One molecule of compound 'Z' on combustion forms two molecules of C02 and three molecules of H20. Identify giving reasons the compounds 'X', 'Y' and 'Z'. Write the chemical equations for all the chemical reactions involved.
Ans. Organic compound 'X' is ethanol, (i.e., CH3 - CH20H).
When ethanol is heated with cone. H2S04 it forms 'Y' which is ethane (CH2 = CH2).
