This is why the implications of MO theory can often be drastically different. For instance, the bond order of an oxygen molecule is found to be 2 in both theories, but VB theory doesn’t explain the paramagnetic properties that oxygen exhibits. Experiments have demonstrated how liquid oxygen is...
Ab initio valence bond calculations are performed for the three lowest states of the oxygen molecule (3危 g , 1螖 g , and 1危+ g ). One objective of the present study was to make a contribution to previous valence bond discussions about the oxygen "double" bond. Further, we study the...
A peptide or amide (–CO–NH–) bond is formed by the linking of the carboxyl group of one amino acid with the amino group of another with the loss of a water molecule. In this bond, the oxygen atom of the carbonyl group is in the trans position with respect to the hydrogen on the...

assigns the oxygen atom a formal charge of +1 and places a double bond between the oxygen and central carbon atom, whereas our algorithm assigns a formal charge of +1 to the central carbon atom and assumes that an oxygen atom bonded to two other atoms will have two lone pairs of ...
Hydrogen atom requires one more electron to attain nearest stable electronic configuration of inert gas (Helium).To achieve this two hydrogen atoms share one electron each to form a single covalent bond. Formation of Oxygen molecule is an example of Double covalent Bond. The atomic number of ...
The amide NH of Gly120 is involved in a conserved hydrogen bond interaction with the reactive N5 center of FAD. Furthermore, the struc- ture reveals that the carbonyl oxygen atom of the adjacent residue, Asn119, forms a hydrogen bond with the side chain of a well ordered lysine residue ...
The H on one water molecule can form a hydrogen bond with the O on another water molecule or with other suitable species.2,3 These hydrogen bonds can be understood in terms of the polarity of the ─O─H bond. Because of the electronegativity difference between the hydrogen and oxygen, the...
It is a type of dipole–dipole bond that describes the attraction between a hydrogen atom and an electronegative element such as nitrogen, oxygen, or fluorine [4,5]. The donor molecule is the one that provides hydrogen, whereas the acceptor molecule is the one that has a lone pair that ...
