Many of the insecticides that contain boric acid will contain a sweetener, such as sugar, to attract insects.
Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.
Intermolecular Bonds (Molecular Materials) Of these three intermolecular bond types, the strongest are hydrogen bonds. For a given size of molecule, chemicals that use hydrogen bonds will tend to have higher melting points and boiling points than chemicals that use the weaker dipole-dipole or van der Waals bonds.
