The VSEPR Valence Shell Electron Pair Repulsion geometry of a molecule with the chemical formula CHCl3 chloroform can be determined by first identifying the central atom and the number of electron groups surrounding it.In CHCl3, the central atom is carbon C . It is bonded to one hydrogen H atom and three chlorine Cl atoms. There are no lone pairs on the central carbon atom. Therefore, there are a total of four electron groups surrounding the central carbon atom.According to VSEPR theory, these four electron groups will arrange themselves to minimize repulsion, resulting in a tetrahedral geometry. The bond angles in a tetrahedral geometry are approximately 109.5 degrees.
