Which of the following accurately describes the nature of the hydrogen atom involved in hydrogen bonding?
Which of the following accurately describes the nature of the hydrogen atom involved in hydrogen bonding?
- It is neutral and has no polar character.
- It forms covalent bonds without interaction with other molecules.
- It is highly polarised and attracts lone pair electrons from electronegative atoms. (correct)
- It carries a positive charge and is involved in ionic bonds.

Study Notes
Hydrogen Bonds
- Hydrogen bonds represent the strongest type of intermolecular force.
- These bonds form between molecules containing hydrogen atoms bonded to highly electronegative elements like fluorine, oxygen, or nitrogen.
- The electronegativity difference results in a highly polarized hydrogen, creating a partial positive charge (δ+).
- This δ+ hydrogen atom is attracted to the lone pairs of electrons on a small, highly electronegative atom in a neighboring molecule.
- These hydrogen bonds bridge two molecules (larger) than the internal covalent bonds within the molecules
- The hydrogen bond is often depicted as a dashed or dotted line.
