Boiling Point of Common Alkanes
The boiling points of alkanes, which are saturated hydrocarbons consisting of carbon and hydrogen atoms with single bonds, increase with the molecular size and weight. The following table provides a comprehensive list of boiling point values for common alkanes at one atmospheric (atm) pressure. (1 atm = 101,325 Pa)
