Which of the following will undergo C-Cl bond homolysis at the highest rate?

Question

Quizplus · Accepted Answer

The bond homolysis of CF1F1F1S1F1F1F10Cl involves the breaking of the weakest bond, which is the bond between the Cl and the adjacent F. This bond undergoes homolytic cleavage to form a Cl- ion and a F1F1F1S1F1F1F1• radical. The stability of the radical formed determines the rate of the reaction, with more stable radicals formed at a faster rate. Among the given options, the D choice provides the most stable radical due to the presence of two electron-withdrawing groups (-CF3) that stabilizes the radical by withdrawing electron density from it. Therefore, CF3CF2CF2CF2CF2CF2CF2CF2CF2Cl undergoes CF1F1F1S1F1F1F10Cl bond homolysis at the highest rate.
