Quizplus · Accepted Answer

The compound has a methyl group attached to the second carbon of a propane chain, and a sulfhydryl group (-SH) attached to the first carbon. Therefore, the correct IUPAC name is 2-methyl-1-propanethiol (D). Choice A and B are incorrect because they refer to isomers of the compound with different alkyl chains. Choice C is incorrect because it uses the incorrect suffix (-thiol instead of -thiol).
