Gradescope 3 This question is worth 8 points. Subdivide one box on your answer sheet into 2 smaller boxes. Label these smaller boxes and For each of the following structures, (1) draw the structure given (2) draw a reasonable resonance structure, (3) use curved arrows to show the flow of electrons for the formation of the resonance structure, and (4) label the resonance structure that is the largest contributor to the resonance hybrid (the major contributor), and briefly explain why....

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.

Two major resonance structures are possible for the following anion. One resonance form is given below, but it is incomplete. Complete the given structure by adding nonbonding electrons and formal charges. Draw the remaining structure, including nonbonding electrons and formal charges. Omit curved arrows. Which structure contributes most to the hybrid? Both contribute equally. The structure with the negative charge on nitrogen. The structure with the negative charge on carbon.

How major resonance structures are possible for the following anion. One resonance form is given below, out it is incomplete. Complete the given structure by adding nonbonding electrons and formal charges. Draw the remaining structure, including nonbonding electrons and formal charges. Omit curved arrows.

5. Draw the number of resonance structures indicated, your structures must fulfill the octet rule. This exercise serves to develop a sense of which Lewis Structures are reasonable so think whether what you are proposing makes sense. Assign formal charges and determine which structure is more likely, major contributor. Draw a box around this structure. Note: it is possible to have more than one major contributor. In that case, indicate these equivalent structures by drawing a box around all of...

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

5. Resonance provides the basis for a large portion of organic chemistry and helps us identify sites of high and low electron density. We will see that the electron source (nucleophile) is attracted to the site of electron sinks or deficiency (electrophile). For the following, draw the curved arrow that shows the movement of electrons that takes you from one resonance structure to the other. Remember to always start your arrow at the source of electrons (r-bond or lone pair)....
