Use (2) curved arrows simultaneously to demonstrate resonance. Select the best possible contributor.

Curved arrows are used to illustrate the flow of electrons. Using the provided resonance structures, draw the curved electron-pushing arrows to show the interconversion between resonance hybrid contributors. Be sure to account for all bond-breaking and bond-making steps.

Identify the most stable radical structure.

1d. 1e.

Complete the following acid-base reaction . Show all valence electrons on the interacting atoms and show by the use of curved arrows the flow of electrons in each reaction.

Criteria for success All molecular drawings must be valid Lewis structures (octet rule, formal charge, valence, geometry). Curved arrows will be interpreted very strictly. Thus, they must clearly indicate the origin and destination of electron delocalization. Tasks 1. Generate at least three reasonable resonance contributors of the molecule in Fig. 3. 2. Rank reasonance contributors from least significant to most significant (#1 = most significant) and explain your choice. 3. Are the lone pairs of electrons on alcohol groups localized or delocalized? Briefly explain. HO OH F Figure 3: Molecule with delocalized electrons

Use curved arrows to show the flow of elections on the reactant side of each of the following reactions

Please help me the the lewis and resoance structures. Draw them out please!! A bond between CO and M, where M is a lewis acid, which forms M-CO. Where M does not have no lone pairs, has one lone pair and two lone pairs.
