EO 3- resonance structures, formal charges, stability
1. Draw ONE possible significant additional resonance structure for each of the following ions. Use curved arrows to show the movement of electrons that creates each new resonance structure. (Hint: lone pairs are not shown. Start by drawing in all one pairs, and include all lone pairs and formal charges in your additional resonance structure.) Page 1 of 3 2. For each structure, draw the resonance structure that is indicated by the curved...
