Solution

a. Substitution Reaction: $C H_{3} - C H_{3} + C l_{2} s u n l i g h t - ---- \to C H_{3} - C H_{2} - C l + H C l$

b. Addition Reaction: $\begin{matrix} {C H}_{2} & = & {C H}_{2} & + & {C l}_{2} & \to & {C H}_{2} & - & {C H}_{2} | & | C l & C l \end{matrix}$

c. Polymerisation: $\begin{matrix} _{n} {C H}_{2} & = & C H & - & C l & \to & {[{C H}_{2} - C H]}_{n} | {C l}_{2} \end{matrix}$

d. Combustion: $C H_{4} (g) + 2 O_{2} (g) \to C O_{2} (g) + 2 H_{2} O (l)$

e. Thermal cracking: $C H_{3} - C H_{2} - C H_{2} - C H_{3} \to C H_{2} = C H_{2} + C H_{3} - C H_{3}$
