A hydrogen bond is an attractive interaction between two species that arises from a link of the form A-H · · · B, where A and B are highly electronegative elements and B possesses a lone pair of electrons. Hydrogen bonding is conventionally regarded as being limited to N, O, and F but, if B is an anionic species (such as Cl− , it may also participate in hydrogen bonding. There is no strict cutoff for an ability to participate in hydrogen bonding, but N, O, and F participate most effectively.——Atkins' Physical Chemistry(2010, 9th ed), p637 |
