Valence Bond Theory (Hybridization) Trigonal Bipyramidal electronic arrangement: AB 5 , AB 4 U, AB 3 U 2 , and AB 2 U 3 Some examples of molecules with this geometry are: PF 5 , AsF 5 , PCl 5 , etc. These molecules are examples of central atoms with five bonding pairs of electrons. The electronic and molecular geometries are the same. Molecules are trigonal bipyramidal and nonpolar when all five substituents are the same. If the five substituents are not the same polar molecules can result, AsF 4 Cl is an example. Trigonal Bipyramidal electronic arrangement: AB 5 , AB 4 U, AB 3 U 2 , and AB
