Intermolecular association in organic nitriles; the CN dipole-pair bond

摘要: The nature of the intermolecular interactions involving CN groups in organic nitriles has been investigated through comparison physical properties and other liquids. Evidence is presented that hydrogen bonding not a significant factor these interactions. tend to associate pairs by dipole interaction, leading partial dimerization mononitriles longer-range association dinitriles. energy interaction between two high, about 8 kcal./mole; it proposed call this dipole-pair bond, analogy with bond. Equations are derived for energies dipoles separated relatively short distances.
