2. What is the most stable anion? Explain your reasoning, using resonance structures, if necessary. Include
   all lone pairs and formal charge. Hint: Consider the resonance of a C=O group and a lone pair of electrons
   with a carbanion versus the resonance of a lone pair next to a lone pair. (5 pts)
