Arrange the following types of intermolecular forces in order of decreasing their strength
(a) Ion dipole
(b) Keesom forces
(C ) Dispersion or London forces
(d) Dipole-induced dipole
(e) lon-induced dipole (Debye forces) .

Explanation

To arrange the types of intermolecular forces in order of decreasing strength, we need to understand each type of force and their relative strengths. Here’s the step-by-step solution:

### Step 1: Identify the Forces
The forces we need to arrange are:
- (a) Ion-dipole forces
- (b) Keesom forces (dipole-dipole forces)
- (c) Dispersion or London forces
- (d) Dipole-induced dipole forces
