Structural isomers of alkanes C₄–C₇ and boiling points

Choose the molecular formula C₄H₁₀, C₅H₁₂, C₆H₁₄ or C₇H₁₆ to see all of its structural isomers (2, 3, 5 and 9 compounds) as condensed structural formulas or skeletal formulas, with the parent chain highlighted and numbered. Each isomer comes with its IUPAC name, its primary/secondary/tertiary/quaternary carbons and its real boiling point; a bar chart shows that the more branched the chain, the lower the boiling point.
