The gas ′A′' A ' is having very low reactivity reaches to stratosphere. It is non-toxic and non-flammable but dissociated by UVUV-radiations in stratosphere. The intermediates formed initially from the gas ′A′' A ' are:The gas ' A ' is having very low reactivity reaches to stratosphere.

Step-by-step 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−ClC - Cl bond.

The gas ' A ' is having very low reactivity reaches to stratosphere. It is non-toxic and non-flammable but dissociated
