Hydrogen Bonds
Part of the Structure and Bonding section of Coddy's Chemistry journey. Lesson 30 of 49.
H bonded to N, O or F has a strong δ+ and is drawn to a lone pair on N, O or F of the next molecule: a hydrogen bond.
A hydrogen bond: H on O, N or F, drawn to a lone pair on O, N or F of the next molecule
It is the strongest force between molecules: water is a liquid while H₂S is a gas.
Challenge
