Question

Quizplus · Accepted Answer

The correct structure for (S)-4-cyclohexyl-3-methyl-2-butanone can be determined by following the IUPAC nomenclature rules for naming organic compounds. In this case, the first step is to identify the parent chain, which is a four-carbon chain with a methyl group attached to the second carbon atom. The carbonyl group is located on the second carbon atom and is therefore numbered as such. The cyclohexyl group is attached to the fourth carbon atom and is named as a substituent using the prefix "cyclohexyl-". The correct stereochemistry is denoted by the (S)- configuration at the stereocenter, which is located on the third carbon atom. The correct numbering of the parent chain and the correct placement of the substituents and stereochemistry result in structure III.
