Answer» erlap of atomic orbits leads to the development of a chemical bond because of the overlap, ELECTRONS are located in the bond region. It describes the “ELECTRONIC structure” of molecules.Postulates:· The “overlap” of two half-filled “VALENCE orbitals” of different atoms leads to COVALENT bond FORMATION. It stabilises the molecule.· If the atomic orbitals have more than one “unpaired electron”, more than “one bond” are formed and “electrons” coupled in the “valence shell” cannot participate in the formation of such a bond.· There are two types of “covalent bonds” according to the overlap pattern such as sigma and pi. The covalent bond formed by the side-overlapping of atomic orbitals is known as the pi bond while the bond formed by atomic orbital overlapping along the “inter-core axis” is known as the sigma bond.· It is directional." |
