Question

Define photolytic reaction by giving examples

Answer 1

Photolysis reactions are initiated or sustained by the absorption of electromagnetic radiation. One example, the decomposition of ozone to oxygen in the atmosphere, is mentioned above in the section Kinetic considerations. Another example is the synthesis of chloromethane from methane and chlorine, which is initiated by light. The overall reaction is

CH4(g) + Cl2(g) + hυ → CH3Cl(g) + HCl(g),
