Question

can anyone explain the concept of valence bond theory plz urgent..

Answer 1

VBD means in a bonding of elements how the atomic orbitals of the dissociated atoms combine to give individual chemical bonds when a molecule is formed. Only half filled orbitals participate. Hybridization is also im

Answer 2

Valence bond and molecular orbital theories are used to explain chemical bonding. Two atoms that have unpaired electrons in their orbitals can overlap to give rise to a chemical bond. A sigma bond (σ ) forms when two atomic orbitals overlap between the nuclei of two atoms (also known as the internuclear axis ).

•Mechanism of Bonding in VB Theory

The VB theory describes the formation of covalent bonds from the overlap of atomic orbitals on two different atoms. Because of the overlap, it is highly probable that a pair of electrons are found in the physical region or space where the orbitals overlap
