The correct IUPAC name for the compound is 1-Butylcyclohexane, as it features a four-carbon butyl chain attached to a cyclohexane ring. The correct answer is option A.
The correct IUPAC name for the compound is 1-butylcyclohexane. This systematic nomenclature is derived by considering the main structural feature of the molecule, which consists of a cyclohexane ring with a butyl group (a four-carbon chain) attached to it.
According to IUPAC naming conventions, when a substituent alkyl chain is longer than the parent cycloalkane, the cycloalkane is named as a substituent using the suffix '-yl'. In this case, 'cyclohexyl' would be considered a substituent if it were attached to a longer chain, but the main chain is the butyl group.
Therefore, the compound is named Butylcyclohexane, with the numerical prefix '1-' indicating the specific carbon atom on the butyl chain to which the cyclohexane ring is attached. This systematic approach to nomenclature ensures clarity and precision in describing the structure of organic compounds.
