The Lewis’s contribution toward understanding the covalent bond to be interpreted. Concept Introduction : Covalent bonding : A covalent bond is formed by sharing of electrons (equally or partially polarized) between the two non-metals. Octet rule: By obtaining eigh...

Covalent bond - Lewis Structures, Electron Sharing, Bonding: The Lewis structures illustrated so far have been selected for their simplicity. A number of elaborations are given below. There is sometimes an ambiguity in the location of double bonds. T
Lewis structures of more complex molecules can be constructed quite simply by extending the process that has been described for hydrogen chloride. First, thevalenceelectrons that are available for bonding are counted (2 × 1 + 6 = 8 in H2O, for example, and 4 + 4 × 7 = 32 incarbon te...
is largelyconfinedto the carbon atom and can be interpreted as being a lone pair occupying an orbital with σsymmetry. This lone pair enables CO to act as a Lewis base and to link to the metal atom by forming a σ bond to it by overlap with one of the lobes of adorbital. However,...
