This article talks about Valence Shell Electron Pair Repulsion (VSEPR) theory in detail. It also talks about different molecular shape. About 1-3 questions are being asked from this topic.

Some of them are- Kössel-Lewis approach, Valence Shell Electron Pair Repulsion (VSEPR) Theory, Valence Bond (VB) Theory and Molecular Orbital (MO) Theory. Let us take a look at the VSEPR theory.

Find the molecular geometry using VSEPR theory Use electronegativity to decide if any bonds are polar ... Valence Shell Electron Pair Repulsion.

The 'classical' shape of four-coordinate nitrogen, carbon and boron compounds is tetrahedral, as predicted by the valence-shell electron-pair repulsion theory that all chemists learn at an early ...

Types of Molecular Geometry . Trigonal planar- In trigonal planar molecular geometry, the center atom has three molecules connected to it. Bond angle is 120 degrees.
