Answer

(a) Methane

(i) Reaction with chlorine: Chloromethane [CH3Cl] and Hydrochloric acid [HCl] are formed when methane reacts with chlorine.

CH4 + Cl2 or 600Kdiffused sunlight\xrightarrow[\text{or 600K}]{\text{diffused sunlight}} CH3Cl + HCl

(ii) Reaction with Bromine : Bromomethane [CH3Br] and Hydrogen bromide [HBr] are formed when methane reacts with bromine.

CH4 + Br2 ⟶ CH3Br + HBr

(b) Ethane

(i) Reaction with chlorine: Chloroethane [C2H5Cl] and Hydrochloric acid [HCl] are formed when ethane reacts with chlorine.

C2H6 + Cl2 ⟶ C2H5Cl + HCl

(ii) Reaction with Bromine : Bromoethane [C2H5Br] and Hydrogen bromide [HBr] are formed when ethane reacts with bromine.

C2H6 + Br2 ⟶ C2H5Br + HBr
