State the postulates of valence bond theory
WebJun 17, 2024 · (a) A covalent bond is formed by the partial overlap of two half-filled atomic orbitals of two atoms. (b) Greater the overlapping of atomic orbitals between the atoms, stronger the covalent bond formed. (c) When a covalent bond is formed, the energy of the molecule decreases and the molecule becomes more stable. According to this theory a covalent bond is formed between two atoms by the overlap of half filled valence atomic orbitals of each atom containing one unpaired electron. A valence bond structure is similar to a Lewis structure, but where a single Lewis structure cannot be written, several valence bond structures are used. Each of these VB structures represents a specific Lewis st…
