Hexane is an organic compound with the chemical formula C₆H₁₄. It is an alkane with 6 carbon atoms. "Hexane" can mean any of the 5 structural isomers (meaning compounds with the same chemical formula but a different shape) it has. IUPAC naming says that "hexane" only means the isomer with no branches, with the other 4 having different names.

There is a lot of hexene in gasoline. Pure hexane has no color and is quite unreactive.
