Van der Waals bonds occur in many molecules, but hydrogen bonds occur only with materials that contain hydrogen. Why is this type of bond unique to hydrogen?
Why hydrogen bonds occur only with materials that contain hydrogen.
Answer to Problem 42.1DQ
The hydrogen bonds occur only with materials that contain hydrogen because only hydrogen has a singly ionized state with no remaining electron cloud.
Explanation of Solution
Explanation:
Hydrogen bond is an attraction between hydrogen bound to a more electronegative atom and another adjacent atom having a lone pair of electrons. It is stronger than van der Waals bond while weaker than ionic and covalent bonds.
In hydrogen bond, a proton gets between two atoms, polarizing them and attracting them by means of the induced dipoles. Hydrogen bond is unique to hydrogen containing compounds because only hydrogen has a singly ionized state with no remaining electron cloud. The hydrogen ion is a bare proton, much smaller than any other singly ionized atom.
Conclusion:
Thus the hydrogen bonds occur only with materials that contain hydrogen because only hydrogen has a singly ionized state with no remaining electron cloud.
