Question

Which of these steps are part mechanism for chlorination of ethane under free radical conditions?

I : C H_{3} C H_{3} + C l^{*} \to C H_{3} C H_{2} C l + H^{*}

I I : C H_{3} C H_{3} + C l^{*} \to C H_{3} C H_{2}^{*} + H C l

I I I : C H_{3} C H_{2}^{*} + C l_{2} \to C H_{3} C H_{2} C l + C l^{*}

I V : 2 C l^{*} \to C l_{2}

Chlorination of ethane occurs in three steps-Chain initiation-Cl2-x2192-Cl-x2217-Cl-x2217-Chain propagation-CH3CH3-Cl-x2217-x2192-CH3CH-x2217-2-HCl
