A reaction in which one atom of a molecule is replaced by another atom (or group of atoms) is called a substitution reaction.

When ethane reacts with chlorine

C2H6 +Cl2 →C2H5Cl + HCl

Chloroethane

C2H5Cl + Cl2 →C2H4Cl2+HCl

Dichloroethane

C2H4Cl2 + Cl2 → C2H3Cl3 + HCl

Trichloroethane

C2H3Cl3 + Cl2 → C2H2Cl4 + HCl

Tetrachloroethane

C2H2Cl4 +Cl2 → C2HCl5 +HCl

Pentachloroethane

C2HCl5 +Cl2 →C2Cl6 + HCl

Hexachloroethane
