What type of intermolecular forces would you expect to find between molecules of H2O? of BrCl? of hexane (C6H14)?

Answer 1

For H2O, hydrogen bonding.
BrCl would be dipole-dipole.
Benzene would be dispersion.

Answer 2

H2O -> dispersion forces, dipole-dipole forces, hydrogen bonding.
BrCl -> dipole-dipole forces.
