Complete your study of acids and bases by searching out the fundamental causes of their disparate behavior. For example, why is there a difference in the ease with which various acids ionize? Your search draws on concepts from previous lectures, including electronegativity, molecular geometry, hybridization, and covalent bonding.

Professor Davis introduces you to ribose, the central component of both RNA and DNA. Starting from individual molecules and motifs, you'll progressively work your way up toward a full model for the structure of the sub-units involved in our genetic code. This lecture is proof of organic chemistry's powerful role in establishing who you are.

Probe the connections between biology and metals with this lecture on some compounds and reactions in the field of organometallic chemistry. As you'll quickly learn, organometallics have a range of practical applications; one example you'll encounter is Dotarem, an organometallic compound used to help detect tumors in cancer patients.

Starting with hydrogen, see how electrons organize themselves within the atom, depending on their energy state. Graduate from Niels Bohr's revolutionary model of the atom to Erwin Schrödinger's even more precise theory. Then, chart different electron configurations in heavier and heavier atoms.

In the first of five lectures on chemical bonds, start to unravel the mystery of what joins atoms into molecules. Investigate how molecular bonds reflect the octet rule encountered in Lecture 7 and fall into four classes: ionic, covalent, polar covalent, and metallic bonds.

In the previous lecture, you delved into strong acids and bases - those that ionize completely in solution. In this lecture, survey weak acids and bases, zeroing in on why they only partially ionize. Practice techniques for calculating their properties and concentrations in various solutions.

Turn now to cyclic alkanes, in which the closing of a loop of carbons forms a whole new class of alkanes with properties all their own. As you learn more about this new class of hydrocarbons, you'll cover the phenomenon of ring strain, the equilibrium between chair conformers, and bicyclic hydrocarbons.

Begin your study of chemical reactions by investigating how chemists write reactions using a highly systematized code. Next, Professor Davis introduces the "big four" types of chemical reactions: synthesis, decomposition, single displacement, and double displacement. He also shows how to translate between measurements in moles and grams.

Make sense of a crucial concept in organic chemistry: the handedness of molecules, or, as chemists call it, "chirality." Topics include the definition of chiral tetrahedral centers; the creation of stereoisomer sets via inversion of handedness; and intriguing examples of stereoisomers (including enantiomers and double-bonded stereoisomers) and their unique chiral centers.

Proteins make up 20 percent of your body's mass. They mediate almost every chemical reaction in the human body, and they're found in everything from medicine to detergents. Here, make sense of the intricate, beautiful structures and interactions of proteins. Also, take a peek at how they're created in labs for further study.
