Hexane vs. Cyclohexane: Know the Difference

By Shumaila Saeed || Published on January 10, 2024

Hexane is a straight-chain alkane with six carbon atoms. Cyclohexane is a cyclic alkane with a ring structure of six carbon atoms.

Key Differences

Hexane is a linear hydrocarbon with the formula C6H14, characterized by its straight-chain structure. Cyclohexane, also with the formula C6H14, differs by having a cyclic, ring-like structure.
