Question

Which of the following is not a possible termination step in the free radical chlorination of methane? CH_3 + Cl_2 rightarrow CH_3Cl + Cl CH_3 + CH_3 rightarrow CH_3CH_3 CH_3 + Cl rightarrow CH_3Cl CH_3 + wall rightarrow CH_3-wall Cl + wall rightarrow Cl-wall In the reaction of Cl_2 with ethane and UV light, which of the following reactions would be a chain termination event(s)? Cl + CH_3-CH_3 rightarrow CH_3-CH_2-Cl + H Cl + CH_3-CH_3 rightarrow CH_3-H_2C + HCl Cl + CH_3-H_2C rightarrow CH_3-CH_2-Cl Cl_2 + CH_3-H_2C rightarrow CH_3-CH_2C1 + Cl Cl_2 + UV light rightarrow Cl + Cl reaction III reactions III and IV reactions I and IV reactions I and II reaction V

Explanation / Answer

14: Option (A) is an example of chain propagation step. Hence option (A) is not a chain termination step.

15: During a chain termination event, two free radicals combine each other to form the product. In reaction III, two different free radicals combine eachother to form the product and hence an example of chain termination event.

Hence option (A) is correct.
