H-bond cooperativity is important, because it often entails mutual strengthening of the H-bonds, and because it can confer specific properties to the molecule [71,72,73,74,75,76]. It is not easy to evaluate the energy of IHBs, because the removal of an IHB causes major changes in the molecule's geometry and, therefore, the energy change...

E-H bonds are simply a way of denoting any bonds you might make between hydrogen and another element. E-H bond strengths are highly dependent on the chemical structure of each element, but many of these bonds are weak — unstable and inclined to break easily and form hydrogen (H 2). Most chemical reactions are driven by the formation of strong...

A coordinate bond (also called a dative covalent bond) is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom. In the formation of a simple or ordinary covalent bond, each atom supplies at least one electron to the formation of the bond - but that is not the case every time.

Ammonia is a compound of nitrogen and hydrogen with the formula NH 3.A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell.

NO is another nitrogen-containing gas molecule, as a free radical which has an unpaired electron in the 2p* antibonding orbital [16,17], thus the N O bond is easy to activate. In recent years, some scholars have tried to use NO as a nitrogen source to synthesize ammonia through electrocatalysis which is named electrocatalytic nitric oxide...

Ammonia has a molecular dipole moment of 14.7 D which denotes the degree of separation between the positively and negatively charged particles. In contrast, HCl has a dipole moment is 1.08 and the water molecule has a dipole moment of about 1.85. Due to this charged polarity ammonia has limited and minimal permeability through lipid membranes.

Furthermore, the shape of the frontier molecular orbitals of Au \(_{79}\) and of the incoming organic molecules has been found to dictate the preferred orientation of the adsorption. Several quantum chemical topological analyses of the electron density have been performed to further classify the interactions to weak dispersive or van der Waals...

The N—H bond in ammonia is quite polar on account of the electronegativity difference of N (3·0) and H (2·1). On the contrary, P—H bond in phosphine is almost non-polar because both P and H atoms have almost same electronegativity (21). Due to polarity, intermolecular hydrogen bonding is present in the molecules of ammonia but not in...
