Lewis structure of the oxide of bromine should be drawn and the hybridization of central oxygen atom should be determined.
Valance bond (VBT) theory: This theory explain a chemical bonding theory that explains the bonding between two atoms is caused by the overlap of half-filled atomic orbitals. The two atoms share each other's unpaired electron to form a filled orbital to form a hybrid orbital and bond together.
Hybridization is the mixing of valence atomic orbitals to get equivalent hybridized orbitals that having similar characteristics and energy.
Geometry of a molecule can be predicted by knowing its hybridization.
Geometry of different types of molecule with respect to the hybridizations are mentioned are mentioned below,
Empirical formula of a compound represents the smallest whole number relative ratio of elements in that compound.
Electronic configuration of in MO term should be written and the HOMO for the molecule should be determined.
Molecular orbital (MO) theory: is a method for determining molecular structure in which electrons are not assigned to individual bonds between atoms, but are treated as moving under the influence of the nuclei in the whole molecule.
According to this theory there are two types of orbitals,
Electrons in molecules are filled in accordance with the energy; the anti-bonding orbital has more energy than the bonding orbitals.
The electronic configuration of oxygen molecule can be represented as follows,
The * represent the antibonding orbital
