Of the given following molecules – BeCl 2 , Br 2 and SF 6 the molecules, whose bonding cannot be explained using Valence bond theory has to be identified. Concept Introduction: Valence Bond theory explains the covalent bonding between atoms. According to Valence bond theory, valence electrons of an atom must be unpaired in ground state. These unpaired electrons are paired with valence electrons of another atom and as a result, covalent bond is formed between the two atoms.

Answer 1

Question

Definition Definition Theory that explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. VBT gives a quantum mechanical approach to the formation of covalent bonds with the help of wave functions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
