Elevation of boiling point Graph Boiling point  :-> The temperature at which the vapour pressure of pure solvent is always less than the vapour pressure of Solution when non-volatile solute is added. Elevation of boiling point Boiling point Elevation constant W hen one mole of solute dissolve in 1 kg of solvent or 1000 g of solvent is called boiling point Elevation constant.

The process of cleavage of C-X bond by ammonia molecule is known as Ammonolysis.
