Solution

1. Compound A Ethene C2H4
2. Compound B Ethane C2H6
3. Compound C 1-Chloroethane C2H5Cl

2. A to B ---Reduction reaction or hydrogenation reaction
B to C --- Substitution reaction

Organic compound A of molecular formula C2H4 is ethane on reduction gives compound B of molecular formula C2H6 ethane. This is a reduction or hydrogenation reaction.
Ni/Pd(reduction)
C2H4 --------------------> C2H6
Ethene(A) Ethane(B)

Organic compound B on reaction with chlorine in the presence of sunlight gives compound C with molecular formula C2H5Cl 1-Chloroethane. This is a substitution reaction.
