ABSTRACT
Molecules that have both hydrogen bond accepting and donating capabilities tend to display physical properties characteristic of higher molecular weight systems (Section C).
Type of interaction Example Magnitude (kJ mol-1)
Covalent H-H 200-800
Ionic Na+ Cl-40-400
Ion-dipole Na+ (H2O)n 4-40
Hydrogen bond H2O...H2O 4-40
Dipole-dipole SO2 SO2 0.4-4.0
