Question

Quizplus · Accepted Answer

The compound is a halogenated alkane with a six-carbon chain. We first need to determine the longest continuous carbon chain, which is six carbons long. Then, we need to assign priorities to the substituents based on their atomic numbers. The highest priority group is the bromine atom, followed by the chlorine atom, and finally the methyl group. Beginning at the end of the carbon chain nearest the highest priority substituent, we number the carbon chain to give the bromine substituents the lowest possible numbers (2 and 3) and the chlorine substituent the next lowest number (4). Finally, we name the compound in alphabetical order, giving the locations of the substituents as prefixes. The correct name is (2R,3S,4S)-3,4-dibromo-2-chloro-3-methylhexane. Therefore, the best choice is B.
