What kind of force is HF?

HF is a polar molecule: dipole-dipole forces. Hydrogen is bounded to F. Hydrogen bonds exist. There are also dispersion forces between HBr molecules. SO2 is a polar molecule: dipole-dipole forces.

Is h2co hydrogen bonding?

In hydrogen bonds, the Hydrogen atom is the hydrogen bond donor, and the atom with the lone pair of electrons is the hydrogen bond acceptor. In the second example, the partially positive end of HF is shown hydrogen bonding to the partially negative portion of formaldehyde (H2CO).

What is the intermolecular force of HCN?

(d) HCN is a linear molecule; it does have a permanent dipole moment; it does contain N, however the nitrogen is not directly bonded to a hydrogen. Therefore dispersion forces and dipole-dipole forces act between pairs of HCN molecules.
