Name EXPERIMENT 15: REPORT MOLECULAR MODELS Sec- tion Procedure In the table below are a series of molecules or ions. You are to make a model of each using the model kit. Your instructor will show you how the model kit is to be used. Once the model is made, you will analyze its structure and fill in the table with the following information: 1 Indicate number of valence electrons and draw the Lewis structure. If there are resonance structures, include only one 2. Draw the VSEPR structure and name the geometry of the electron regions Name the molecular geometry and approximate bond angles. 4. Draw the VSEPR structure again, indicating the polarity of the bonds with arrows by considering the relative electronegativities of the atoms. Is the molecule orion polar overall, yes or no? 6. An example showing NH, is shown in the first set of boxes. Refer to the introduction for more info on NH; 3 5.

Yes iz trigonal pyramid NH, example H 8 N . AB3E1 - total of 4 re- gions = tetrahedral N H H Н Н н <1090 EN-H H SeCl2 H Asly SiBr H30* CF3H CO, BrCN (is the central atom) PO, SO2- CH,O (formaldehyde Oz (ozone) N3 (azide ion) Discovery Question: draw all possible Lewis formulas of CH2Cl (the two C atoms are central). You may find isomers". How are these structures different? Examine models. Predict whether each of the structures will have a molecular polanty.
