What role does the molecular interaction play in a solution of alcohol and water?
Suggest the most important type of intermolecular attractive interaction in the following pair.
Acetonitrile (CH3CN) and acetone (C3H6O)
Vapour pressure of pure acetone and chloroform at 328 K are 741.8 mm Hg and 632.8 mm Hg respectively. Assuming that they form ideal solution over the entire range of composition, plot Ptotal, `P_"chloroform"` and `P_"acetone"` as a function of `chi_"acetone"`. The experimental data observed for different compositions of mixtures is:
| `bb(100 xx chi_"acetone")` | `bb(P_"acetone"//"mm Hg")` | `bb(P_"chloroform"//"mm Hg")` |
| 0 | 0 | 632.8 |
| 11.8 | 54.9 | 548.1 |
| 23.4 | 110.1 | 469.4 |
| 36.0 | 202.4 | 359.7 |
| 50.8 | 322.7 | 257.7 |
| 58.2 | 405.9 | 193.6 |
| 64.5 | 454.1 | 161.2 |
| 72.1 | 521.1 | 120.7 |
Plot this data also on the same graph paper. Indicate whether it has a positive or negative deviation from the ideal solution.

Which of the following gave the idea of a nucleus of the atom?
Lowering of vapour pressure of an aqueous solution of a non-volatile, non-electrolyte 1 molal aqueous solution at 100°C is ______.
Suggest the most important type of intermolecular attractive interaction in the following pair.
