Q6 / 90 · JEE Main 2021 (27 Aug Shift 1) · Chemistry

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:

Solution

The gas is Chloro-fluoro carbon. In presence of UV radiation it follows free radical mechanism. Formation of free radical as intermediate occurs due to homolytic fission of C-Cl bond.
