Free radical chlorination of ethane can produce higher halogenation products such as dichloroethane, trichloroethane, tetrachloroethane, pentachloroethane, and hexachloroethane. How could the production of higher halogenated products be minimized?

Question

Quizplus · Accepted Answer

By using an excess of ethane, the concentration of free radicals in the reaction mixture will decrease. This will decrease the likelihood that multiple chlorination events will occur, resulting in the production of higher halogenated products. Using an excess of chlorine (choice A) or equimolar chlorine and ethane (choice C) will not necessarily minimize the production of higher halogenated products. Choice D is incorrect, as it is possible to minimize the production of higher halogenated products by adjusting reaction conditions.
