📘 Effect of Increasing Carbon Chain Length (Number of Carbon Atoms)

PropertyTrend with Higher Carbon CountReason (Short Note)
Boiling Point⬆️ IncreasesStronger intermolecular (van der Waals) forces
Melting Point⬆️ Generally increasesLarger molecules pack better
Molecular Mass⬆️ Increases by 14 u per –CH₂–Each –CH₂– adds 12 (C) + 2 (H)
Density⬆️ Slightly increasesHeavier and more closely packed molecules
Viscosity⬆️ IncreasesLonger chains tangle more
Water Solubility⬇️ DecreasesNon-polar nature increases
Reactivity➖ Nearly sameFunctional group remains same
Chemical Behaviour➖ SimilarBelong to same homologous series
