Pick out the wrong statement. Raoult's law does not apply, when the______________________?
Correct answer: D. Component molecules are non-polar
- A. Size of component molecules are not equal
- B. Attractive forces between like and unlike molecules in the solution are approximately equal
- C. Chemical combination or molecular association between unlike molecules takes place in the
- D. Component molecules are non-polar
- E. formation of solution
Explanation
Non-polar components with similar molecular size and comparable intermolecular forces tend to form nearly ideal solutions, so Raoult's law is more applicable. Molecular association or chemical combination between unlike molecules causes deviation, making the non-polar statement the wrong one.
