Hexane is a hydrocarbon that contains a chain of six single-bonded carbon atoms with the rest of the bonds taken up by hydrogen atoms. The ending -ane means the all of the carbon atoms are single-bonded. The chemical formula is ##"C"_6"H"_14"##. The image below shows the structural formula.

Hexene is also a six carbon hydrocarbon, but there is a pair of carbon atoms that are double-bonded. The ending -ene means that there is a double bond between two carbon atoms. There are several isomers of hexene based on the location of the double bond. The chemical formula of hexene is ##"C"_6"H"_12"##. The following diagram is the structural formula for 1-hexene. The name means that the double bond is between the first and second carbon atoms.
