How do you name a cyclic alkane with six carbons?

To name a cyclic alkane with six carbons, the correct terminology involves recognizing both the structure and the specific naming conventions for cyclic compounds. In this case, a six-carbon cyclic alkane is termed cyclohexane.

Cyclohexane is a saturated hydrocarbon, which means that all carbon-carbon bonds are single bonds and it follows the general formula CnH2n for alkanes. For six carbon atoms, n equals six, leading to the formula C6H12. The prefix "cyclo" indicates that the carbons are arranged in a ring structure, which is crucial to differentiating cyclic alkanes from their straight-chain counterparts.

The other terminology in the options reflects different types of hydrocarbons: hexane refers to a straight-chain alkane with six carbons (C6H14), cyclopentane has only five carbons in a ring, and hex-1-ene describes a straight-chain alkene with six carbons, specifically indicating the presence of a double bond. Each of these alternatives addresses different structures or bonding types, thereby confirming that cyclohexane is the correct name for a cyclic alkane with six carbons.
