![]() The most stable resonance form is one that provides the lowest formal charge of the atoms. The resulting combined configuration may be shown with a dashed line. The electrons within the molecule are said to be delocalized and can be found with equal probability within any of these resonance structures. In general, the bonds within such a molecule are assumed to be a combination of all of these resonance structures. A molecule that displays resonance may have electrons in any of these resonance configurations at any given time. A resonance structure is an alternative model of covalent bonding. One advantage to using a Lewis dot diagram is that resonance structures can be shown. Be sure to understand these terms well, as they will be high-yield on Test Day! At the end of this guide, there are also several MCAT-style questions you can use to test your knowledge. Throughout this guide, there will be several important terms marked in bold. Some exist between individual atoms of a molecule, while others exist between molecules. There are a variety of bonds, or attractive forces, that exist. Atomic bonds and intermolecular attractions are the foundation for many additional concepts in organic chemistry and biochemistry.Ĭhemical bonds are chemical interactions that create an attractive force between atoms or molecules. Understanding how atoms and molecules interact with each other is crucial for much of the chemistry section of the MCAT. What holds everything in the universe together? Why don’t atoms and molecules randomly split apart and float away? The answer lies in bonding and molecular interactions. Part 1: Introduction to bonds and interactions ![]()
