Boiling Points of Alkanes Reminder about Alkanes: . Alkanes are chemical compounds that consist only of the elements carbon (C) and hydrogen (H) in proportions according to the general formula: C n H (2n+2) where the letter n represents the number of carbon atoms in each molecule. The atoms that form alkanes are linked exclusively by single bonds, hence alkanes are saturated hydrocarbons.
