Subdivide one box on your answer sheet into 2 smaller boxes. I abel these smaller boxes as A and B. 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. A ich B H

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.

Three major contributing resonance structures are possible for the following anion. One is given below, but is incomplete. Complete the given structure by adding non-bonding electrons and formal charges. Draw the remaining structures, including non-bonding electrons and formal charges. Do not draw curved arrows.

a See page 1127 13 Question (3 points) When naphthalene undergoes an irreversible electrophilic aromatic substitution, the major product is the kinetic product, which proceeds through the most stable arenium ion intermediate. With this in mind, draw the curved arrow mechanism for the first step of the electrophilic aromatic substitution of naphthalene with the acylium ion generated from acetyl chloride and AlClg, Then draw the curved arrows and a resonance structure in step 2 with an unbroken benzenoid ring.Draw all...

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)....
