In the next two questions, we will tackle resonance structures. A combination of resonance structures more accurately describes a particular molecule and helps us better understand the electronic nature of the compound of interest. Instead of just guessing what a resonance structure will look like, it is helpful to draw the arrows leading from one structure to the next. There are a few things you should keep in mind. There are two important "commandments" that you can never violate when pushing arrows. a Thou shall not break a single bond b. Thou shall not violate the octet rule. Draw the curved arrows that get you from one resonance drawing to the next. When you draw arrows, you must begin at the source of electrons such as lone pairs and pi bonds. If you are using pi bond electrons, begin your arrow halfway across the bond. In the following resonance structure problems, draw the resulting resonance structure after pushing the arrows shown. Be sure to include formal charges. Draw in all lone pairs of electrons.
