Chemistry 222-500 Spring 2007 Hybrid Orbitals and Multiple Bonds 1. Consider the acetonitrile molecule: a. Predict the bond angles around each carbon atom b. Give the hybridization at each of the carbon atoms c. Determine the total number of σ and π bonds in the molecule 2. Consider this structure of glycine, the simplest amino acid. Note: lone pair electrons are NOT shown in this structure. a. What are the approximate bond angles about each of the two carbon atoms, and what are their hybridizations? b. What are the hybridizations of the two oxygen atoms and the nitrogen atom, and
