The mixture which shows positive deviation from Raoult’s law is
Options
- ABenzene Toluene
- BAcetone Chloroform
- CChloroethane Bromoethane
- DEthanol Acetone
Correct answer
D. Ethanol Acetone
Step-by-step solution
In solutions showing positive deviation partial pressure of each component A and B is higher than that calculated from Raoult's
law, and hence total pressure over the solution is also higher than if the solution were ideal.
The intermolecular interaction is weaker as interaction found in any one of the pure components.
Hydrogen bond of ethanol gets weakened by addition of acetone.
