Considering the formation, breaking and strength of hydrogen bond, predict which of the following mixtures will show a positive deviation from Raoult’s law?
1. Methanol and acetone
2. Chloroform and acetone
3. Nitric acid and water
4. Phenol and aniline
1. | Less than the boiling point of water but more than the boiling point of ethanol |
2. | More than the boiling point of water but less than the boiling point of ethanol |
3. | More than the boiling point of ethanol as well as water |
4. | Less than the boiling point of ethanol as well as water |
1. | Mole fraction of A in the vapour phase is more than the mole fraction of A or B in liquid phase |
2. | Mole fraction of A or B in the vapour phase is more than the mole fraction of A or B in liquid phase |
3. | Mole fraction of A or B in the vapour phase is same as the mole fraction of A or B in liquid phase |
4. | Mole fraction of A and B in the vapour phase is less than the mole fraction of A or B in liquid phase |
