3: Representations of Organic Molecules
( \newcommand{\kernel}{\mathrm{null}\,}\)
- 3.1: Structural Formulas - Lewis, Kekule, Bond-line, Condensed, and Perspective
- Here you will learn how to understand, write, draw, and talk-the-talk of organic molecules. Organic molecules can get complicated and large, so o-chemists have developed short hand notations to communicate structure.
- 3.2: Isomerism Introduction
- Structural (constitutional) isomers have the same molecular formula but a different bonding arrangement among the atoms. Stereoisomers have identical molecular formulas and arrangements of atoms. They differ from each other only in the spatial orientation of groups in the molecule.
- 3.3: Resonance
- Resonance delocalizes shared electrons over three or more atoms to lower the electron density and stabilize the compound or ion.
- 3.4: Organic Functional Groups
- Functional groups are to organic chemistry what ions are to general chemistry. We simply must be able to recognize and distinguish between functional grouops to learn organic chemistry.
