VSEPR theory stands for Valence Shell Electron Pair Repulsion which tackles on the resulting geometry of molecule according to the number of electron pairs surrounding their central atoms.
The general formula of compounds indicating electron groups is:
Where A is the central atom
X represents the atoms attached to A
n is the number of atoms attached to A
E represents the lone pairs around A
m is the number of lone pairs around A
Use the VSEPR method to predict the molecular shape of the following species. Show all your reasoning.
