VSEPR
The VSEPR (Valence Shell Electron Pair Repulsion) theory is a fundamental concept in chemistry, providing a model for predicting the shapes of molecules based on the repulsion between electron pairs in the valence shell of an atom. This theory, developed by Gillespie and Nyholm in the 1950s, is crucial for understanding molecular geometry and the behavior of molecules in chemical reactions. By considering the arrangement of electron pairs around a central atom, VSEPR theory allows chemists to predict the three-dimensional shapes of molecules, which in turn influences their properties and reactivity.

- VSEPR theory tells that the valence electron pairs stay as far from each other as possible. For example, in BeCl_2 the two electron pairs of the two bonds are far apart so why we don't do this in the case of a double bond and assume it as a single bond ??
