Welcome to Organic chemistry. It's the branch of chemistry that helps us create new medicines, develop innovative materials, and unlock the secrets of life itself. From the food we eat to the clothes we wear, organic chemistry is everywhere.
Let's review the basics of chemical bonds including dot structures, hybridization, bond-line structures, electronegativity, and polarity. We will also discuss how bonding and intermolecular forces relate to physical properties such as boiling point.
Just like how your left foot doesn't quite fit your right shoe, molecules also can have properties that depend on their handedness! This property is called chirality. We will go over what makes a molecule chiral, stereoisomers, assigning configurations using the R,S system, optical activity and Fischer projections.
- [Voiceover] In this video, we're going to find the oxidation state of carbon in several different molecules. In earlier video, we've already seen the definition for oxidation state, and also how to calculate it.

So if we extend this definition to chemistry, because that's what we're talking about, there's two concepts here. There are chiral molecules, and then there are chiral centers or chiral-- well, I call them chiral atoms.
- Now that we know how to assign oxidation states to Carbon let's look at some organic redox reactions, and remember these definition from general chemistry. Oxidation involves an increase in the oxidation state and reduction involves a decrease or a reduction in the oxidation state.
