Question

An organic compound X on heating with conc. H2SO4 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 CO2 and three molecules ofH2O. Identity giving reasons the compounds X, Y, Z.W rite the chemical equations for all the chemical reactions involved.

Answer 1

X-Ethanol
Y-Ethene
Z-Ethane
C2H5OH-->CH2-CH2+H2O
CH2-CH2+H2-->C2H6
C2H6+O2-->2CO2+3H2O
