n-Pentane, n-Hexane, and n-Heptane are homologous alkanes (C5H12, C6H14, C7H16) differing in carbon chain length, leading to increased molecular weight, stronger London dispersion forces, higher boiling points, and lower vapor pressures as you go from pentane to heptane, making pentane most volatile (used in foams/aerosols), hexane a common solvent (oil extraction/cleaning), and heptane a fuel standard/solvent (coatings/analysis).
