2. Use the VSEPR theory to predict the shapes of the following molecules or ions. First, draw the Lewis structures for each species. Next, use the modeling kit to build the molecule and confirm that it matches your Lewis structure. For structures 2a e, show your models to your instructor. Finally, report the molecular geometry and bond angles for each of the central atoms. H bol H с с с CN H Central Atom Molecular Geometry Bond Angles Carbon (left)...
Pick 10 polyatomic ions. Draw Lewis strucures for each(1). Include major resonance forms (2) with formal charges (3). Identify the VSEPR notation (4), shape (5), and hybridization (6) of the central atom(s) of each molecule or ion. List all types of van der Waal forces expected in a pure sample of each molecule (7).
