Quizplus · Accepted Answer

The parent chain contains six carbon atoms, making it a hexanoyl chloride. The two methyl groups are on the 2 and 4 positions or 3 and 5 positions (counting from the carboxyl carbon atom), so the correct name is either 2,4-dimethylhexanoyl chloride or 3,5-dimethylhexanoyl chloride. The substituent on the second carbon atom is an ethyl group, indicating the correct answer is D, "F1F1F1S14-F1F1F10ethyl-3,5-dimethylhexanoyl chloride."
