Quizplus · Accepted Answer

The reaction looks like a substitution reaction with the reagent being some sort of halogen (possibly Br2 or Cl2). In III, the reactant has a double bond and a substituent, so it can undergo an electrophilic addition reaction with Br2 or Cl2. The halogen will add to the double bond to form a halogenated alkane with a substituent. None of the other reactants have a double bond or a substituent to undergo this reaction, so III must be the correct choice.
