Problem Set 7 KEY Dr. Sparks, CH 301, Fall 2010 These you should be able to do now: 1. Draw dot structures for the following species and answer these questions for each: Does the molecule exhibit resonance? How many bonding pairs are in the molecule? How many lone pairs on in the molecule? Assign formal charges for each atom in the molecule. a. Ozone, O 3 Yes, it has 2 resonance structures 3 bonding pairs 6 lone pairs (Note that you were asked for the number of lone pairs. If you had been asked for the number of nonbonded electrons, that would have been 12. Make sure you pay attention to what you are asked for.) Formal charges are shown in the structure. You do not need to show these to have a correct structure; it is just an easy way for us to post the answers. b. Ammonia, NH 3 No resonance structures 3 bonding pairs 1 lone pair All formal charges are zero. c. HCN No resonance structures 4 bonding pairs 1 lone pair All formal charges are zero. d.
