Vedclass · Answer

(C) Colligative properties are those properties of a solution that depend only on the number of solute particles present in the solution,regardless of their nature.There are four main colligative properties:$1$. Relative lowering of vapour pressure.$2$. Elevation in boiling point.$3$. Depression in freezing point.$4$. Osmotic pressure.Among the given options,vapour pressure itself is a physical property,but the 'relative lowering of vapour pressure' is the colligative property. Therefore,'vapour pressure' is not a colligative property.
