QAIPMT-2006-Ch-2392: NEET 2006 Chemistry - Class 12 AIPMT-2006-Ch-2392 Solution: A solution of acetone in ethanol
A solution of acetone in ethanol
Multiple Choice Options
- A obeys Raoult's law
- B shows a negative deviation from Raoult's law
- C shows a positive deviation from Raoult's law
- D behaves like a near ideal solution.
Step-by-Step Verified Solution
A solution of acetone in ethanol shows
positive deviation from Raoult's law. It is because
ethanol molecules are strongly hydrogen
bonded. When acetone is added, these
molecules break the hydrogen bonds and
ethanol becomes more volatile. Therefore its
vapour pressure is increased.
