each of the following structures can potentially react with NEGATIVELY charged molecules. Use resonance forms to identify the site (s) on each molecule that would be attracted to an atom with NEGATIVE charge 5.10b Each of the following structures can potentially react with negatively charged molecules. Use resonance forms to identify the site(8) on cach molecule that would be attracted to an atom with a negative charge. i) 1
Draw Lewis structures to determine which of the following compounds exhibit resonance. Enter the letters corresponding to all those compounds which exhibit resonance. (If you find that choices A, C, and F all have resonance and the others do not, for example, you would enter ACF as your answer. Make sure the letters you enter are in alphabetical order, with no spaces or commas separating them.) 2. Draw Lewis structures to determine which of the following compounds exhibit resonance. Enter...

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)....
