Q. No.The interaction energy of London force is inversely proportional to sixth power of the distance between two interacting particles. Their magnitude depends upon-
1. Charge of interacting particles.
2. Mass of interacting particles.
3. Polarizability of interacting particles.
4. Strength of permanent dipoles in the particles.
Dipole-dipole forces act between the molecules possessing permanent dipole. Ends of dipoles possess 'partial charges'.
The partial charge will be-
1. More than unit electronic charge.
2. Equal to unit electronic charge.
3. Less than unit electronic charge.
4. Double the unit electronic charge.
Given below are two statements:
| Assertion (A): | Three states of matter are the result of a balance between intermolecular forces and the thermal energy of the molecules. |
| Reason (R): | Intermolecular forces tend to keep the molecules together but the thermal energy of molecules tends to keep them apart. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | (A) is false but (R) is true. |

| (a) | Complete order of molecules |

| (c) | Random motion of molecules |
| (d) | Fixed position of molecules |
1. (a, b)
2. (b, c)
3. (c, d)
