Question

Quizplus · Accepted Answer

The initiating step for mechanism 1 is the homolytic cleavage of the chlorine molecule to form chlorine radicals, which can then react with ethane to start the chain reaction. The initiating steps for mechanisms 2 and 3 involve UV light, which may not be present in the reaction conditions, and therefore are not as likely to occur.
