Lewis structures give atomic connectivity –which atoms are physically connected to which in a molecule, but not the shape and size of the molecule The shape of a molecule is determined by its bond angles and bond length --- consider CCl 4 molecule below experimentally we find all Cl-C-Cl bond angles are 109.5 ° . Thus, the molecule cannot be planar – cannot be predicted from Lewis structure drawing 9.1 Molecular Shapes 9.1 Molecular Shapes Tetrahedron object Ball-and-stick model Space-filling model
