Geometry of Molecules : VSEPR Theory
Geometry of molecules : VSEPR theory is one of the most common topics for academic examinations like IIT-JEE and NEET as well as for academic examinations. In fact, VSEPR theory is helpful in deciding the geometry of covalent molecules. It was first proposed by Powel and then modified by Gillispie and Nyholm. This theory decides the geometry of those polyatomic covalent molecules in which all the atoms or groups remain attached to the central atom only by single bond but not by multiple bonds i.e. double or triple bonds.
