The General Formula of Alkanes is C(n)H(2n+2).

Boiling Point decreases with less chains.

The more carbon atoms, the greater the intermolecular Van Der Waals' Forces.

The melting point of alkanes increase with the molar mass.

Alkanes are miscible with water.

Alkanes always combust completely forming Carbon Dioxide and water.

Cracking is the process at which large carbon chained alkanes break into smaller alkanes and alkenes.

Via free radical substitution with halogen and UV, room temperature and H3PO4, Alkanes become Haloalkanes.

Heated under pressure with H2 and a Nickel catalyst, Alkanes become Alkenes.

Alkanes are fairly unreactive, strong non-polar covalent bonded molecules.
