1. An organic compound A on heating with concentrated H2 SO4 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 two moles of CO2 and 3 moles of H2O. Identify the compounds A, B and C and write the chemical equations of the reactions involved.

Question

1.	An organic compound A on heating with concentrated H2 SO4 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 two moles of CO2 and 3 moles of H2O. Identify the compounds A, B and C and write the chemical equations of the reactions involved.

Accepted Answer

Soln:
Compound A is Ethanol Compound A = CH3CH2OH
CH3CH2OH conc. H2SO4 CH2-CH2+ H2O
Compound B is Ethane Compound B = CH2= CH2 CH2=CH2 Ni C2H6
Compound C = CH3 &mdash; CH3 2C2H6+7O2 4CO2 +6H2O
