CHEMISTRY 0320 - ORGANIC CHEMISTRY II Prof. C. S. Wilcox - University of Pittsburgh Unit 1 Reading: Chapter 14 I. Molecular Orbitals. a. Orbitals represent potential places for electrons. The pictures of orbitals that we use show the locations in a molecule where the probability of finding an electron (if the orbital is occupied) is high. b. When "N" atomic orbitals combine, "N" new molecular orbitals are formed and take the place of the original orbitals. II. The "2-P" system. a. The student should review the pi bond (double bond). Two p-orbitals combine to form two pi orbitals. One is bonding, one is anti-bonding. III. The "3-P" system. The allylic cation, allyl radical, and carboxylate. a. Be able to draw the three molecular orbitals for a 3-P species and be able to show how these orbitals may be filled with two, three, or four electrons. Which are bonding, which are antibonding? b. Be able to write resonance forms for the allylic cation, allylic radical, or carboxylate ion. Compare resonance representations of these ions with the highest occupied
