Hydrogen Bonding
Captions available
The idea
Hydrogen bonding is a strong dipole-dipole attraction between an H bonded to F, O, or N and a lone pair on a neighboring F, O, or N atom.
In practice
Water boils far higher than the H2S-H2Se-H2Te trend predicts, since only water can hydrogen bond.
Where people slip
Hydrogen bonding requires H bonded directly to F, O, or N — a C-H hydrogen does not qualify.
