Cyclohexane: A cycloalkane of molecular formula C₆H₁₂, consisting of six methylene groups forming a ring. The most stable conformation of cyclohexane is the chair conformation.

Molecular Structure of Cyclohexane

Chair conformations of methylcyclohexane. Note that when the chair flips, the methyl group (shown in red) shifts between an equatorial position (on the left side of the equilibrium) and an axial position (on the right side of the equilibrium).
