Question

what kind of intermolecular forces act between a water molecule and a hydrogen fluoride molecule? note: if there is more than one type of intermolecular force that acts, be sure to list them all, with a comma between the name of each force.

Explanation:

Both water ($\ce{H2O}$) and hydrogen fluoride ($\ce{HF}$) are polar molecules with hydrogen bonded to highly electronegative atoms (oxygen in $\ce{H2O}$, fluorine in $\ce{HF}$). So, hydrogen bonding occurs between them. Additionally, all molecules experience London dispersion forces (also called van der Waals forces or induced - dipole induced - dipole forces), so these are also present.

Answer:

hydrogen bonding, London dispersion forces
