which statement is true for dipole-dipole forces?

they are stronger than hydrogen bonding forces.
they are weaker than london dispersion forces.
they occur between ions and polar molecules.
they occur between polar molecules.

They occur between polar molecules.

Explanation:

Dipole-dipole Forces act between polar molecules that is  between  molecules that possess dipole moments. It is electrical interactions between polar  molecules. The larger the dipole moments, the greater the  force.H-bonding is a special type of dipole-dipole forces that is between H-atom and an electronegative atom such as: N, O, F.Dipole-dipole Forces are stronger than London dispersion forces.

So, the right choice is: They occur between polar molecules.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
