Explanation / Answer
We Know that : Lower the bond - dissociation energy easier tocleave the the bond between the atoms. When CF3CHClF is bombared withhigh - energy photon the Product C is formed as the cleavageof C-Cl bond is very easy which can be interpretedfrom their bond energy. CF3CHClF + photon ---------> CF3CHF + Cl
