Organic Chemistry VSEPR Theory and Hybridization VSEPR Theory VSEPR stands for Valence Shell Electron Pair Repulsion Theory. We use VSEPR to predict the 3D shapes of the molecules made by the 2nd period elements. The main focus in this topic is going to be on the carbon (C), nitrogen (O), and oxygen (O). Those three elements make the “core” of the organic molecules, so you’re going to be working with those most of the time. How Do We Apply the VSEPR Theory? The premise of the VSEPR is the idea that the electron pairs & bonds will distribute themselves as … VSEPR Theory Read More »
