The incorrect statement among the following is:
| 1. | Two different solutions of sucrose of the same molality prepared in different solvents will have the same depression in freezing point. |
| 2. | The osmotic pressure of a solution is given by the equation π = CRT (where C is the molarity of the solution) |
| 3. | Decreasing order of osmotic pressure for 0.01 M aqueous solutions of BaCl2 > KCl > CH3COOH > sucrose |
| 4. | The vapour pressure exerted by a volatile component of a solution is directly proportional to its mole fraction in the solution. |

The incorrect statement among the following is:
| 1. | Units of atmospheric pressure and osmotic pressure are the same. |
| 2. | In reverse osmosis, solvent molecules move through a semipermeable membrane from a region of lower concentration of solute to a region of higher concentration. |
| 3. | The value of molal depression constant depends on nature of solvent. |
| 4. | Relative lowering of vapour pressure, is a dimensionless quantity. |
