Answer 1

Answer:

(a) Hydrogen bonding

(b) Dispersion forces

(c) Ion-dipole forces

(d) Dipole-dipole forces

Ion-dipole forces (c) are the strongest of the 4 interactions while dispersion forces are the weakest (b).

Explanation:

The picture is missing but I think is the one that I'm uploading.

Picture (a)

HF is a polar molecule with a high difference in electronegativity between H and F. As a consequence, the force between HF molecules is Hydrogen bonding.

Picture (b)

In picture (b) we have F₂ molecules, which are nonpolar due to their atoms having the same electronegativity. The forces between nonpolar molecules are dispersion forces.

Picture (c)

Na⁺ is an ion and H₂O a dipole. Therefore, they experience ion-dipole forces.

Picture (d)

SO₂ molecules are polar, that is, they form dipoles and experience dipole-dipole forces.

Ion-dipole forces (c) are the strongest of the 4 interactions while dispersion forces are the weakest (b).
