What types of intermolecular forces exist between nh3 and cbr4?

In nh3, intramolecular forces would be covalent bonds in the simple covalent molecule. Intermolecular forces would be hydrogen bonds and temporary dipole induced dipole interactions. In cbr4, it is a jin polar molecule as the dipole moment is cancelled out by the 4 bromine atoms hence it only has temporary dipole induced dipole interactions

C) electrons encircling a nucleus with neutrons and protons
