CHEM 222 Chapter 2 Homework 1. What are the shapes of the methyl cation (CH 3 + ) and the methyl anion (CH 3 - )? Would you classify the methyl cation as a Lewis base (nucleophile)? 2. Which of the following will have a larger O-N-O bond angle, NO 2 or NO 2 - ? 3. For the compound shown below: N O OH O N a) Indicate sp and sp 2 -hybridized carbons in the structure b) What is the hybridization state of the ketone carbon? c) What is expected bond angle for the circled region? d) Locate an example of a highly polarized covalent single bond e) Identify the functional groups in the molecule f) Indicate with an asterisk the most basic site in the molecule 4. Write structural formulae for all alkenes with molecular formula C 2 H 2 Br 2 and C 2 Br 2 F 2 . Predict the dipole moment of each compound.
