Ratio of the amount of solute in organic and aqueous solvent is________________?
Correct answer: B. Distribution co-efficient
- A. Retardation factor
- B. Distribution co-efficient
- C. Distribution in aqueous solution
- D. All statements are wrong
Explanation
The distribution coefficient is the ratio of a solute's concentration, or amount under specified conditions, in two immiscible solvents such as organic and aqueous layers. Students may choose the retardation factor because it is also a ratio used in separation, but Rf belongs to chromatography, not liquid-liquid partitioning.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
