In this section we will study how the atoms that make up a molecule are arranged in space. This spatial arrangement (molecular geometry) affects the physicochemical properties of the substance (melting and boiling point, solubility.....)
Although the determination of molecular geometry must be done experimentally, there is a simple method for losing molecular geometry, called the valence shell electron pair repulsion (VSEPR) method. This method is based on arranging the bonds, which start from a central atom, so that the repulsions between the bonding electrons are as low as possible.
