A breakthrough by researchers at The University of Manchester sheds light on one of nature's most elusive forces, with ...

so even though it contains polar bonds, the molecule itself is non-polar and the only intermolecular force present will be weak London dispersion forces. Ammonia (NH 3) and hydrogen fluoride (HF ...

When comparing molecules of the same size, the type of intermolecular forces present need to be considered by looking for O-H or N-H bonds (hydrogen bonding) or polar bonds (permanent dipole ...
