1 / -0

An important product in the ozone depletion by chlorofluorocabons is

A
$$ Cl_2$$

B
$$ OCl $$

C
$$ F_2 $$

D
$$ O_2F_2 $$

Solution

$$CFCl_3$$ + electromagnetic radiation $$\rightarrow Cl^{\bullet}+ CFCl_2^{\bullet}$$
$$Cl^{\bullet} + O_3 \rightarrow ClO + O_2:$$The chlorine atom changes an ozone molecule to ordinary oxygen.
$$ClO + O_3 \rightarrow Cl^{\bullet} + O_2:$$The ClO from the previous reaction destroys a second ozone molecule and recreates the original chlorine atom, which can repeat the first reaction and continue to destroy ozone.
So, the correct answer is option B.
