How do you know when to draw a solid wedge vs a dashed wedge when drawing 3D bond-line structures? I know that solid-wedge means the atom is pointing towards you and dashed wedge means it's in the back, but how do you know which atoms are in the front as opposed to the back? How can you tell what the configuration will look like in space just by looking at the lewis structure or name?

2. In biologically relevant molecules, carbon and the halogens don't have a charge. In contrast, nitrogen (neutral or positively charged) and oxygen (neutral or negatively charged) don't always appear in their uncharged form. Consider the following questions. a. Add any unshared pairs of electrons necessary to complete the Lewis structure shown for formaldehyde (note: there are no formal charges in this molecule). b. Assign any formal charges necessary to complete the structure shown for the acetylide anion. c. Recalling that atoms want a complete octet, add unshared pairs of electrons, and assign formal charges as appropriate to the Lewis structure of the amino acid aspartic acid as it would exist at a physiological pH of ~7.4 (aspartic acid has an overall -1 charge at this pH).

Draw a Lewis structure of your choice that has at least three equally reasonable resonance structures. You must show your work as to how the structure was drawn including showing valence electrons, any structures you draw that don’t work and require you to show a multiple bond, and formal charges on each atom that has a formal charge. For example, Nitrate ion has three structures (but you can’t draw this one). All three structures have formal charges and no one structure is preferred based on formal charge. Carbon dioxide would not be a valid choice. While it does have three structures, the structure that has two double bonds is the preferred structure while the structures with triple bonds are not equivalent to the double bonded version as they have multiple formal charges present.
