What happens to freezing point of benzene when small quantity of napthalene is added to benzene?
- Increases
- Remains unchanged
- First decreases and then increases
- Decreases
The Correct Option is D
Solution and Explanation
On addition of naphthalene to benzene, there is a depression in the freezing point of benzene. This is due to the presence of a non-volatile solute (naphthalene), which lowers the freezing point.
