Quizplus · Accepted Answer

Isobutyl mercaptan is a thiol with a butane backbone and a sulfur atom attached to the second carbon atom. To name this compound following IUPAC nomenclature, we first need to identify the longest continuous carbon chain, which is four carbons long. The sulfur atom is considered the functional group, so we add the suffix "-thiol" to the name of the parent chain. To indicate the position of the sulfur atom, we number the carbon chain starting from the end closest to the functional group, which in this case is the second carbon atom. The name of the compound derived from the given structure is 2-methyl-1-propanethiol.
