(a)
Interpretation: The mechanism for monochlorination with the help of iodobenzene dichloride should be proposed.
Concept introduction: The monochlorination performed with ultraviolet light proceeds via radical chain mechanism. Chlorine transforms
The mechanism for monochlorination comprises of three stages illustrated as follows:
Step1- Initiation via homolytic cleavage of
Step2-: Propagation: In first of the propagation steps,
In subsequent propagation step chloromethyl radical abstracts
Step3: Termination: Radicals generated in propagation steps get quenched upon combination with one another. Thus termination steps are essentially the radical− radical combination illustrated as follows:
(b)
Interpretation: The three major sites of monochlorination present over steroidsshould be predicted.
Concept introduction: The monochlorination performed with ultraviolet light proceeds via radical chain mechanism. Chlorine transforms
