Question 2

The chlorofluorocarbon (CFC) CFCl3\text{CFCl}_3CFCl3​ (trichlorofluoromethane) contributes to the depletion of the ozone layer in the stratosphere.

Which initiation step occurs when CFCl3\text{CFCl}_3CFCl3​ absorbs ultraviolet radiation?

A

CFCl3→∙F+∙CCl3\text{CFCl}_3 \rightarrow \bullet\text{F} + \bullet\text{CCl}_3CFCl3​→∙F+∙CCl3​

B

CFCl3→∙Cl+∙CFCl2\text{CFCl}_3 \rightarrow \bullet\text{Cl} + \bullet\text{CFCl}_2CFCl3​→∙Cl+∙CFCl2​

C

CFCl3→∙C+∙FCl3\text{CFCl}_3 \rightarrow \bullet\text{C} + \bullet\text{FCl}_3CFCl3​→∙C+∙FCl3​

D

CFCl3→∙Cl2+∙CFCl\text{CFCl}_3 \rightarrow \bullet\text{Cl}_2 + \bullet\text{CFCl}CFCl3​→∙Cl2​+∙CFCl
