Unformatted text preview: ABU 3 Species (Three Lone Pairs of Electrons on A) Linear molecules – only 2 atoms. Neither VSEPR nor VB theory adds to understanding. There may be debate whether the “central” atom is hybridized or unhybridized. Some examples of molecules with this geometry are: HF, HCl, HBr, HI, FCl, Ibr Electronic and molecular geometries are different due to lone pairs. Molecules are linear and polar when the two atoms are different. – Cl 2 , Br 2 , I 2 are nonpolar.
