The order of circled C - H bond dissociation energy in the following compound is

Options

AII > I > IV > III
BIV > III > I > II
CI > II > IV > III
DI > IV > II > III

Correct answer

C. I > II > IV > III

Step-by-step solution

Bond dissociation energy or bond energy (BE) of C - H bond of a hydrocarbon (R H ) can be predicted from stability of free radical (R^ ) formed by homolytic bond fission of C - H bond of the hydrocarbon. Stability order of free radicals (C)>(D)>(B)>(A)
