  3. 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

. 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.
 

Best Answer

Answer: 

Compound A is Ethanol
 
Compound A = CH3CH2OH
 
CH3CH2OH (in the presence of conc. H2SO4) → CH2-CH2+ H2O
 
Compound B is Ethane
 
Compound B is CH2= CH2
 
CH2=CH2 (in the presence of Ni)  →C2H6
 
Compound C = CH3 — CH3
 
2C2H6+7O2 4CO2 +6H2O
