The strength of intermolecular forces between two benzene molecules is approximately equivalent to that between two toluene molecules.
| (a) | ΔHmix= Zero |
| (b) | ΔVmix = Zero |
| (c) | They will form a minimum boiling azeotrope |
| (d) | They will not form an ideal solution |
Identify the incorrect statements (from a to d given above) regarding a mixture of benzene and toluene:
| 1. | a and b | 2. | b and c |
| 3. | c and d | 4. | a and d |
The solution that follows Raoult’s law is known as the ideal solution. For an ideal solution, intermolecular forces between two benzene molecules are nearly the same strength as those between two toluene molecules. For an ideal solution, ΔVmix = 0 and ΔHmix = 0 Thus, the mixture of benzene and toluene is an example of an ideal solution, so statements c and d are incorrect. Hence, the correct option is the third option. |
