As we learned

 

Vapour Pressure -

It is defined as pressure exerted by vapours on liquid surface at equilibrium and condensation.

-

 

 Vapour pressure\alpha \frac{1}{Boiling point}

When vapour pressure decreases then b.pt. increases.


Option 1)

An increase in the b.p. of the solution

Option 2)

A decrease in the b.p. of the solvent

Option 3)

The solution having a higher freezing point than the solvent

Option 4)

The solution having a lower osmotic pressure than the solvent
