O Macmillan Learning (a) Draw two resonance structures of the cation shown, shifting only one electron pair in each step. Be sure to include the formal charge on structures B and C. Only move one double bond. Each resonance structure should contain only one charge-a positive charge. resonance structure B resonance structure A (b) Use curved-arrow notation on the given structure A to show its conversion to structure B, and then on structure B to show its conversion to structure C. 1.

Draw all resonance contributors for each of the following molecules or ions. Be sure to include the curved arrows that indicate which pairs of electrons are shifted in going from one resonance structure to the next. (a) CH3NO2 (b) CH, CO, (c) CH CHCHCH2 (the ion has two C-C single bonds) (d) C5H5N (a ring is formed by the C and N atoms, and each H is bonded to a C atom) (e) C4H5N (a ring is formed by the C and N atoms, and the N is bonded to one H atom, and each C atom is bonded to one H atom)
6. (a) In structure 3 of Model 2, the double bond electrons move to form a lone pair on oxygen. The arrow below shows the double bond electrons moving to form a lone pair on carbon. Draw the resulting resonance form (make sure to put in charges). HC :O: CH₂ 3 (b) Although this form is possible, it is not likely. As a group, discuss why the lone pair is more likely to reside on oxygen than on carbon. 7. Follow the resonance structure guidelines developed in question #4 above. For each pair below, determine whether the resonance structure on the right is an acceptable resonance structure of the form on the left. Place an X through any incorrect structures on the right of each pair, and indicate which of the items listed in question 4 were not followed. Once everyone in your group agrees, draw a correct resonance form. :0 [R-1 H H 4 H H CH₂ CH₂ |- N POGIL www.FOOIL.ORG

I had gotten this one incorrect, but i wanted to use it to study, so please give me the solution to all parts of this question.
A) 1) One of the following four structural formulas is not a permissible resonance contributor which one? Why? на HC на a) b) NFO c) H₂C HC H.C H₂C ks 2) Using curved arrows, show the electron movement that connects the three resonance contributors. لوج شركة السار NFO
The curved arrow notation introduced in Section 1.6B is a powerful method used by organic chemists to show the movement of electrons not only in resonance structures, but also in chemical reactions.Because each curved arrow shows the movement of two electrons, following the curved arrows illustrates what bonds are broken and formed in a reaction. Consider the following three-step process. (a) Add curved arrows in Step [1] to show the movement of electrons. (b) Use the curved arrows drawn in Step [2] to identify the structure of X. X is converted in Step [3] to phenol and HCl.
For the following structure a) draw curved arrows and generate two (2) more valid resonance structures in addition to the initial structure given Be sure to include to show lone pairs and formal charges on your resonance structures. b) Rank the resonance structures in order of decreasing importance: 1 is most important, 2 is second most important, 3 is the least important :0
