Final answer:
Hydrogen bonding describes the attraction between the oxygen of one water molecule and the hydrogen of another, forming a bond due to their opposite charges and polar nature.
Step-by-step explanation:
The bonding illustrated when the oxygen of one water molecule bonds with the hydrogen of another water molecule is known as hydrogen bonding. This occurs due to opposite electrical charges attracting one another, where the partially positive hydrogen atom is attracted to the partially negative oxygen atom of a neighboring molecule. Water molecules are polar because of the highly electronegative oxygen atom, which creates a dipole interaction.
Each hydrogen bond is indicated with a dotted line in diagrams because they are relatively weak compared to covalent bonds, which are represented by a solid line. In a water molecule, the hydrogen and oxygen atoms are held together by covalent bonds, but hydrogen bonds form between different water molecules due to the attraction between the charges.
