The name of the alkane isomer of cis-3-hexene is:A. 2-methylpentaneB. 3-methylpentaneC. n-hexaneD. cyclohexane

Alkane Isomers
An alkane isomer would be a saturated hydrocarbon (containing only single bonds) that has the same molecular formula as cis-3-hexene. The molecular formula for hexene (C₆H₁₂) is C₆H₁₃ for alkanes, as alkanes have all single bonds.

Possible Options
A. 2-methylpentane - This is an alkane with a molecular formula of C₆H₁₄.
B. 3-methylpentane - This is also an alkane with a molecular formula of C₆H₁₄.
C. n-hexane - This is a straight-chain alkane with the molecular formula C₆H₁₄.
D. cyclohexane - This is a cyclic alkane with the molecular formula C₆H₁₂.
Analysis
The only compound listed that has the same molecular formula as cis-3-hexene (C₆H₁₂) is D. cyclohexane (C₆H₁₂).
Conclusion
The alkane isomer of cis-3-hexene is D. cyclohexane.
