CHEM 1405-Experimend 7s Shapes of Molecwies Section:Date: Name: Post Lab Questions 1. Using the methods you learned in this lab, determine the molecular geometry of the central atom in the following molecules/ions. In the case of molecules, determine whether they are polar or not. Approximate Polar or Bond angles nonpolar? of electron Electron Molecule Lewis formula lon NH, so, HCN CH CI H.O 2. Do you expect the H:0 molecule's actual bond angle (between one O-H bond and the other) to be greater than, equal to, or smaller than the angle indicated by the electron arrangement? Why? (Hint- review the background information regarding VSEPR) 12
