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...

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.

9.2 Molecules and Charge 2. Indicate the total number of valence electrons in the following ions: NH4+ PO43− NO2− H3O+ 3. In the following structures, one atom has a nonzero formal charge. Locate that atom, and indicate the charge. 4. Draw Lewis structures for the following ions. Show formal charges where appropriate. PH4+ NO3− BrO− CO32− 5. Thiocyanate, SCN−, can be drawn in two resonance structures, shown below. Calculate the formal charge on each atom of the two forms.
methyl isocyanate, shown as resonance structure 1
(a) Draw two resonance structures of the cation shown, shifting only one clectron 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. (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 curved arrows to show conversion of resonance...
