Homework Answers
There are certain rules, you need to follow strictly as written below
1. In order to have resonance structure in a given molecule, there must be conjunction in the molecule, that is there should alternate π bond, separated by only one single bond or one π bond and lone pair again separated by only one single bond
2. If you find conjunction, then draw resonance structure by shifting either π bond or lone pair, any atom should not be shifted, you should not break any sigma bond while drawing resonance structure.
3. For second period element like N, O, F, octet rule must be followed, that there should not be more than 8 electron around them, less than 8 is acceptable but not more

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)....

Draw Lewis structures for the following molecule and ions. For each of these structures
a) Draw Lewis structures for the following molecule and ions. For each of these structures, the octet rule must be satisfied, and all lone pairs must be shown. Name the molecular geometry for each and also specify if they are polar. If a molecule has more than one resonance structure, draw just the best one. Show formal charges only if they are not zero. b) Which compound(s) above will not have ideal bond angles about the central atom? Circle your choice(s). CNF ...

WHATS THE ANSWER?
When drawing resonance structures, the most stable resonance structure is the one in which: O All atoms have a formal charge. O If there are formal charges, like charges are as close as possible. O Negative formal charges are on the least electronegative atoms. O Positive formal charges are on the least electronegative atoms. Next
