Question

1. which type of intermolecular force is present between any molecules?

london - dispersion force
covalent bonds
dipole - dipole force
hydrogen bonds

Explanation:

London - dispersion forces are present between all molecules. They result from temporary dipoles caused by the motion of electrons. Covalent bonds are intramolecular, not intermolecular. Dipole - dipole forces occur between polar molecules, not all molecules. Hydrogen bonds are a special type of dipole - dipole force and are not present between all molecules.

Answer:

London - dispersion force
