Why about eq.3 one mole of C on combustion forms 2 moles of CO2 and 3 moles of H2O.

We are given that the compound B on addition of one mole of H2 in the presence of Ni forms another compound. This suggests that the compound B is unsaturated. Since the compound B is formed by dehydration of compound A by using H2SO4, it means that compound A is an alcohol. Compound C will be alkane (alkenes on hydrogenation give alkanes). As compound C gives two molecules of CO2 and three molecules of H2O, it means that it is an alkane containing two carbon atoms. Thus
Compound A = CH3CH2OH
Compound B = CH2=CH2
Compound C = CH3-CH3
Following are the chemical equations for the reactions
