From the following which point is not relevant with valence bond theory?
(A) One half filled orbital of one atom overlap with half filled orbital of other atom
and forms covalent bond.
(B) The combining atoms share their valence electrons and form covalent bond.
(C) By overlapping electrons become paired in valence orbital's
(D) According to valence bond theory co-ordinate covalent bond is not formed
between two atoms.

Valence bond theory states that overlap between two atomic orbitals forms a covalent bond between two atoms.

Key Points
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 ).
Pi bonds (
π
) occur when two atomic orbitals overlap outside of the space
