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).
