I think so. In order to have a dipole-dipole force, you must have polar bonds within a molecule that don't cancel out (essentially the molecule is polar). Dipole-induced dipole, however, exists among polar and non-polar molecules.
Yes, because in order for there to be a nonzero net charge of the molecule, there has to be a dipole moment involved. These variances in dipole moments cause molecules to be polar and therefore they involve themselves in dipole-dipole interactions.
Yes, however, nonpolar molecules can have temporary dipoles.
Yes, because the temporary negative charge on an atom in a molecule will react with a temporary positive charge on a different atom in another molecule, which creates a dipole-dipole interaction between the two polar molecules.
Will we need to draw dipole moments on the exam?
yes, because of the partial charges
Yes due to the partial charges. Nonpolar molecules can have temporary dipoles.
You should show that one of the atoms is pulling the electrons their direction giving it a slight charge.
