CHEM 3A Problem Set 2 (January 30, 2009 ) NOTE: No problem sets will be turned in for 3A lecture! A. Write a Lewis structure for acetonitrile, C 2 H 3 N, which contains a carbon-nitrogen triple bond. How many electrons does N have in its valence shell? How many are involved in bonding in this molecule? What is the hybridization on each C atom? B. The chemical phosgene, Cl 2 C=O, is one of the more infamous chemical warfare agents used in World War I. Explain why it is less polar than formaldehyde, H
