When explaining hydrogen bonds, water is always used as an example. When water is used as an example, why is it named hydrogen bond instead of oxygen bond?

Because water is the most common in life, and the formation of hydrogen bonds is due to the fact that both molecules have highly electronegative atoms, and in addition to the bonding electrons, these two atoms also When unbonded electrons meet together, they will form a weak force, which we call a hydrogen bond. . .
