(a)
Interpretation: The reason behind hydrogen abstraction by chlorine rather than bromine atoms even when equimolar amount of each is present should be explained.
Concept introduction: The monochlorination performed with ultraviolet light proceeds via radical chain mechanism. Chlorine transforms
The fundamental radical chain mechanism is summarized in the illustration below:
