In a homologous series, physical properties such as melting and boiling points exhibit a gradation with increasing molecular mass. This trend is observed because larger molecules generally have stronger intermolecular forces, leading to higher melting and boiling points.

In a homologous series, physical properties exhibit a systematic change with increasing molecular mass. As the number of carbon atoms in the chain rises, there is a corresponding increase in molecular mass. Consequently, physical properties like melting and boiling points display a gradation, generally escalating with higher molecular mass. This trend is attributed to enhanced van der Waals forces and intermolecular interactions in larger molecules. Solubility in specific solvents also follows a similar pattern. The systematic variation in physical properties across the homologous series provides a predictable framework for understanding and categorizing organic compounds with similar functional groups.
