Hydrocarbons compounds

Hydrocarbons: fuels, solvents, and homologous series

Methane, propane, butane, hexane, octane, and benzene form a ladder from natural gas to gasoline to aromatic feedstocks. Molar mass rises with chain length, changing boiling point and fuel energy per mole. Benzene’s aromaticity changes reactivity, not the atom-counting rules for molar mass.

Compare C₃H₈ vs C₄H₁₀ for LPG, C₈H₁₈ for octane rating context, and C₆H₆ for aromatic chemistry.
