'''Alkanes''' are substances that belong to a homologous series of [[organic]] compounds that contain the elements [[carbon]] and [[hydrogen]] only, and whose members differ by constant relative [[molecular mass]] of 14. In an alkane, each carbon atom and hydrogen atom are held together saturated covalent bonds; the general molecular formula for alkanes is C_nH_2n+2. In contemporary industrial societies, these [[hydrocarbon]]s are most often as [[fuel]]s and to produce chemicals, such as [[methane]] and [[octane]]. These chemicals are derived from the fractional [[distillation]] of [[crude oil]] and via [[catalytic cracking]].

Alkanes are insoluable in water, and have a lower density thus making them float atop water.

When alkanes have more than 4 carbon atoms, they are named using a greek numeral prefix plus '''-ane''' suffix, e.g. pentane (C₅H₁₂), hexane (C₆H₁₄).
