An organic compound A on heating with concentrated H2SO4 forms a compound B which on addition of one mole of hydrogen in presence of Ni forms a compound C. One mole of compound C on combustion forms 2 moles of CO2 and 3 moles of H2O. Identify the compounds A, B and C and write the chemical equations of the reactions involved.

Answer :

Compound A is ethanol (C2H5OH).

Compound B is ethane (C2H4).

Compound C is ethane (C2H6).

The following equations show the reactions involved in this process.

C2H5OH + conc. H2SO4 C2H4 + H2O

C2H4 + H2 + Ni C2H6

2C2H6 + 7O2 4CO2 + 6H2O + Heat and light
