1.(10 points) Consider the reactive intermediate below: A) In the space below draw all significantly contributing resonance structures (including lone pairs). Use curved arrows to indicate the flow of electrons between the resonance structures. b) In the resonance structures you have drawn above, predict which one will be the most stabilized resonance contributor. Discuss briefly (1 sentence) why you chose this structure to be the most stable contributor to the resonance hybrid.
3. (20 points) For each of the molecules or ions in question 2. there is one additional important resonance structure many one additional important resonance structure that can be drawn. Use curved arrows to show the formation of the new resonance structure from the first, and draw the new structure. Indicate med stability of the two structures in each case, and briefly explain your reasoning
