WebFeb 23, 2024 · Hydrogen atoms in water molecules are attracted to regions of high electron density and can form weak linkages, called hydrogen bonds, with those regions. This means that the hydrogen atoms in one water molecule are attracted to the nonbonding electron pairs of the oxygen atom on an adjacent water molecule. WebH 2 O has a tetrahedral arrangement of molecules or an angular geometry. This is mainly because the repulsion from the lone pair combination is more than bond-pair repulsion. Additionally, the existing pairs do not lie in the same plane. One pair is below the plane and the other one is above.
