CHEMISTRY 121 1 Department of Chemistry University of British Columbia Problem Set 11 Molecular Orbital Theory 1. When atomic orbitals combine to form molecular orbitals, the number of molecular orbitals formed is: (a) equal to the number of atomic orbitals (b) twice the number of atomic orbitals (c) half the number of atomic orbitals (d) not determined by the number of atomic orbitals (e) none of the above 2. Which combination of atomic orbitals would result in the following molecular orbital? Sketch the atomic orbitals involved and be sure to show phases (+ or -) 3. The compound sodium peroxide (Na 2 O 2 ) is an industrial bleaching agent for fabrics and paper products. This important industrial chemical contains the peroxide ion, (O 2 ) 2– . (a) Give the full molecular orbital configuration for the peroxide ion. (b) What is the oxygen-oxygen bond order in the (O 2 ) 2– ion? 4. The E region of the ionosphere is 50-90 miles above the surface of the earth. This region of the earth's atmosphere has been probed by means of satellites. A variety
