Question:

The gas ‘A’ is having very low reactivity reaches to stratosphere. It is non–toxic and non–flammable but dissociated by UV—radiations in stratosphere. The intermediates formed initially from the gas ‘A’ are :


Correct Option: , 4

Solution:

In stratosphere CFCs get broken down by powerful

UV radiations releasing$\mathrm{Cl}^{*}$

$\mathrm{CF}_{2} \mathrm{Cl}_{2}(\mathrm{~g}) \stackrel{\mathrm{U} \cdot \mathrm{v}}{\longrightarrow} \mathrm{Cl}^{*}(\mathrm{~g})+{ }^{*} \mathrm{CF}_{2} \mathrm{Cl}(\mathrm{g})$
