Name two intermolecular forces that exist between $HF$ molecules in the liquid state.

(N/A) $HF$ is a polar covalent molecule that exhibits dipole-dipole interactions due to the electronegativity difference between $H$ and $F$. Additionally,because $F$ is a highly electronegative atom bonded to $H$,$HF$ molecules also exhibit hydrogen bonding. Therefore,the two intermolecular forces present between $HF$ molecules in the liquid state are $1.$ Hydrogen bonding and $2.$ Dipole-dipole interactions.
