Concept Introduction:
According to VSEPR (Valence Shell Electron Pair Repulsion) theory, each molecule gets a unique structure. That structure is explained by considering steric number of that molecule.
The geometry of the central atom will be determined by counting the steric number followed by the hybridization state of that central atom and finally electronic arrangement of atoms in space.
The steric number is the combination of both number of
If the steric number is 4, the central atom is sp3 hybridized and the electronic arrangement of atoms in space (i.e. geometry) will be tetrahedral.
If the steric number is 3, the central atom is sp2 hybridized and the electronic arrangement of atoms in space (i.e. geometry) will be trigonal planar.
If the steric number is 2, the central atom is sp hybridized and the electronic arrangement of atoms in space (i.e. geometry) will be linear.
