Final answer:
The molecular formula of cyclohexane is C6H12, which refers to its composition of six carbon atoms and twelve hydrogen atoms in a ring structure with only single bonds.
Step-by-step explanation:
The molecular formula for cyclohexane, which consists of 6 carbon atoms and 12 hydrogen atoms, is C6H12. Cyclohexane is a ring-shaped molecule, and unlike the compound described with a double bond, cyclohexane contains only single bonds between its carbon atoms. Therefore, the description provided seems to pertain to cyclohexene or another cyclic compound with double bonds, not cyclohexane. Cyclohexene, which has one double bond, would have the molecular formula C6H10.
