Document Summary

Section 2. 2 bond-line structures: bond-line structures are easy to read and draw where carbon atoms and most hydrogen atoms aren"t drawn. This notation is used very frequently in representing organic processes. Section 2. 3 identifying functional groups: a functional group is a characteristic group of atoms/bonds that show a predictable chemical behavior. Functional groups present in organic compounds determine the compound"s reactions. A negative charge on the carbon means there is a lone pair of electrons. Lone pairs are often not drawn in bond-line structures. It is important to recognize that these lone pairs are present. In bond-line structures, a wedge represents a group coming out of the page, and a dash represents a group behind the page. 3d structure: other drawings used to show three dimensionality include fischer projections (acyclic compounds) and haworth projections (cyclic compounds). Section 2. 8 curved arrows: curved arrows are tools for drawing resonance structures.
