Vsepr I Molecular Model Kit

Kit Contents: 5 white 1-peg hydrogen atom centers 3 blue 4-peg nitrogen atom centers 4 red 4-peg oxygen atom centers 3 green 4-peg halogen atom centers 2 black 4-peg carbon atom centers 2 yellow 4-peg sulfur atom centers 8-1.25" PVC, clear bonds (single bonds) 8-1.625" PVC, clear bonds (double bonds) Background information booklet, Lab procedure, student response form, and answer key PDF on this website. The accompanying booklet explains the geometry of valence electron pairs, based on VSEPR theory, and molecular shape using ABE notation. Instructions are given for drawing correct Lewis structures of several molecules which can then be built with this kit. The lab procedure calls for students to make examples of linear, bent triatomic, tetrahedral, and trigonal planar molecules.
