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...
Draw two resonance structures for the following molecule, using arrows to show the movement of electrons.
5. For each structure below, draw the best additional resonance structures. The mmber of additional resonance structures that you need to draw are indicated by the number of resonance arrows in each bracket for a given structure. It would be helpful to show my missing lone electrod pairs Don forget to include formal charge where applicable. (2pts for each correct resonance structure) Don't Completely understand the Resonance structure.
Add curved arrows to both resonance structures of nitromethane to show the delocalization of electron pairs. A curved arrow starts at an electron source (lone pair or bond) and points to an electron sink.
3. Using curved arrows draw all the significant (not negligible) contributing resonance structures for the ions or molecules given below. (curved arrows must show how each proposed structure is generated) a) (5 points) b) (5 points) compond ОН n abom nl ( c) (5 points) 24
4. Consider the molecule BF3. Two possible resonance structures are shown below. :: a) Use curved arrows to show electron movement. b) Assign formal charges to each resonance contributor. c) Are both structures equally contributing to the resonance hybrid? Which is the better structure and why?
3 Three major contributing resonance structures are possible for the following anion. One is given below, but is incomplete. Complete the given structure by adding non-bonding electrons and formal charges. Draw the remaining structures, including non-bonding electrons and formal charges. Do not draw curved arrows.
4) Provide all the Resonance structures of the Cycloheptatrienyl Cation, using arrows show the flow of electrons (delocalization) in each resonance structure. (2 points)
4. Dr raw resonance structures for each of the following compounds. Use curved arrows to show the movement of electrons. A) (4 points) :O B) (5 points) C) (6 points)
