Which of the following is defined as the attractive forces between polar molecules? i. dispersion forces; ii. dipole-dipole interactions; iii. ion-dipole interactions

II. dipole-dipole interactions

Explanation:

Intermolecular forces are the forces between molecules, they are responsible to the molecules forms a compound, the physical state, the boiling point, etc.

When the molecule is polar it means there are partial charges, so there will be an interaction with a positive partial charge of one molecule and negative partial charge of another molecule. They form a dipole because there is a positive and a negative pole. So the interaction is dipole-dipole.

When the molecule is apolar, to form the bonding, a pole must be induced, so, the interaction is dipole-induced-dipole-induced.

If a dipole-dipole bonding is formed between hydrogen and the most electronegative atoms (N, O, and F) the bonding will be extremally strength and it will be called hydrogen bonding.

If there is an ion in the molecule, the force will be ionic or only ion.
