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.
Figure 21 Illustrates hydrogen bonding between two water molecules as observed in water. The hydrogen bonds are short, linear and strong. These are two-center hydrogen bonds. Although each water molecule in liquid water and in ice forms four hydrogen bonds, only one hydrogen bond is shown here.
