Interpretation: The theory thatexplains the paramagnetism of
Concept introduction:
Lewis structures are two dimensional structures showing the lone pairs and bond pairs present in a molecule.
The VSEPR model helps in predicting the shape of molecules on the basis of their Lewis structures.
The
The concept of hybridization of atomic orbitals explains the observed bond angles and geometry of a molecule. The concept of hybrid orbitals explains the formation of required number of orbitals with unpaired electron that can participate in the bond formation.
Molecular orbital theory helps in predicting the magnetic properties of molecules. Paramagnetic substances contain unpaired electrons while diamagnetic substances contain paired electrons.
