Question

what type of intermolecular forces is/are present in hf? * london dispersion forces only dipole - dipole forces only london dispersion forces and dipole - dipole forces dipole - dipole and hydrogen bonding dipole - dipole, hydrogen bonding, and london dispersion forces ionic ionic and london dispersion forces

Explanation:

1. London - Dispersion forces are present in all molecules as they result from temporary - induced dipoles due to the motion of electrons.
2. HF is a polar molecule because of the large electronegativity difference between H and F, so dipole - dipole forces exist.
3. Hydrogen bonding occurs in HF as H is bonded to a highly electronegative F atom.

Answer:

E. dipole - dipole, hydrogen bonding, and London dispersion forces
