Question

Quizplus · Accepted Answer

1,2 addition of HCl adds the chloride ion to the carbon that has the most hydrogen atoms. In the given molecule, that would be the middle carbon of the double bond. The resulting structure would have the chloride and the remaining hydrogen on adjacent carbons, resulting in a 3-chloro compound. The methyl group remains on the same carbon as before, so the correct answer is 3-chloro-3-methyl-1-hexene.
