Re: Question about interactions
Yes, dipole-dipole interactions can exist for molecules with only two atoms, such as hydrogen fluoride. In a molecule like HF, the hydrogen atom has a partial positive charge, and the fluorine atom has a partial negative charge. This charge separation is due to the difference in electronegativity between the two atoms. The electronegativity of fluorine is higher than that of hydrogen, meaning fluorine has a stronger tendency to attract electrons. As a result, the shared electrons in the HF molecule are drawn more toward the fluorine atom, creating a dipole moment. Dipole-dipole interactions occur when the positive end of one polar molecule is attracted to the negative end of another polar molecule. In the case of HF, the partial positive charge on the hydrogen atom can interact with the partial negative charge on the fluorine atom in adjacent HF molecules.
