Chemistry 2090 Homework #7 Please hand in the following problems at the beginning of class on October 24. 1. Draw Lewis dot structures, including appropriate resonance forms, and assign formal charges to each of those structures, for the following species: (a) HNC (the N atom is in the center) (b) SCN (the C is in the center) (c) H 2 CNN (the Frst N atom is bound to both the C and the second N; the H’s only to C) 2. Consider the molecule NNO.

Unformatted text preview: (a) Use VSEPR theory to predict the shape of the molecule. (b) It is found that the molecule has a small dipole moment. Using what you know about molecular geometry, and electronegativity, and formal charge(s) suggest which end of the molecule has the partial positive charge. In addition, attach the answers to the following questions found in our text: Chapter 10: 22, 46, 52, 60 1...
