SECTION 1: 1. PF3CL2 is a nonpolar molecule. Based on this information, determine the F-P-F bond angle, the Cl-P-CL bond angle, and the F-P-Cl bond angle. Answer: PF3Cl2 is trigonal bipyramidal with bond angles of 90 and 120 degrees. If PF3Cl2 is nonpolar then the F atoms must all be in the equitorial positions and the chorines in the axial position. The F-P-F bonds must be 120 degrees, the Cl-P-Cl bond angle is 180 degrees, and the F-P-Cl bond angle is 90 degrees. Which statement best describes the polarity of ? Answer: CF2Cl2 is always polar. Which statement best describes the polarity of ? Answer: SF4Cl2 is octahedral. If the F atoms were all in the same plane and the Cl atoms opposite each other, then the molecule would be nonpolar. Any other arrangement would be polar. Therefore it depends on the arrangement whether the molecule is polar or nonpolar. SECTION 2: 1. Compare the bond enthalpies of the carbon-carbon single, double, and triple bonds. Based on this information, what is the average pi-bond contribution to bond enthalpy
