Web23 jul. 2024 · Even though a hydrogen bond is only 5% as strong as a covalent bond, it's enough to stabilize water molecules. Hydrogen bonding causes water to remain liquid over a wide temperature range. Because it takes extra energy to break hydrogen bonds, water has an unusually high heat of vaporization. WebA hydrogen bond is a strong intermolecular force between a hydrogen atom bonded to an electronegative atom, and a lone pair of electrons on another electronegative atom, namely oxygen, nitrogen or fluorine. A hydrogen bond forms when a hydrogen atom bonded to a relatively electronegative atom acts as a hydrogen bond donor.

Web14 feb. 2024 · Which hydrogen bond has the strongest bond? The strongest H−X bond is definitely between hydrogen and fluorine. Fluorine is a first row element; it makes sense that there is better overlap between fluorine/hydrogen orbitals, than between chlorine/hydrogen orbitals. WebIn H2O strong hydrogen bonding is present which makes it a liquid. In H2S and H2Se weak intermolecular forces are present. Therefore H2S and H2Se are gases at room temperature. The boiling point of HBr is higher than HCl It is due to the bigger size of bromine than chlorine.
