Options
- ABoiling point of pure water decreases by the addition of ethanol.
- BVapour pressure of pure water decreases by the addition of nitric acid.
- CVapour pressure of pure benzene decreases by the addition of naphthalene.
- DBoiling point of pure benzene increases by the addition of toluene.
Correct answer
D. Boiling point of pure benzene increases by the addition of toluene.
Step-by-step solution
Boiling point of a pure solvent increases by increase in number of soluble particles present in it. So by addition of toluene, boiling point of pure benzene increases.
