Description
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.

Description
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.

Transition to the other side of the visible spectrum and discover how infrared spectroscopy provides chemists with different information about structures. In doing so, you'll come to see molecular structures in a new light: not as rigid constructs but as dynamic, vibrating frameworks with bonds that can stretch and bend.

In this final lecture on spectroscopic techniques, discover the importance of modern NMR spectrometers, which use superconducting magnets and radio receivers to collect spectra with more speed and precision (and in different ways) than other techniques. Also, get an intriguing lesson in the human element - and limitations - involved in spectroscopy.

Explore alkyl halides, hydrocarbons where one or more hydrogen atoms are replaced by a halogen atom. You'll examine how larger halogen atoms decrease the volatility of alkyl halides compared to their alkane counterparts (which radically changed the science of refrigeration). You'll also learn about the reactivity of alkyl halides and the phenomenon of carbocation rearrangements.

Chromatography - in which partitioning between stationary and mobile phases leads to predictable rates of movement for compounds - is one of the most powerful separation techniques ever developed. And, when done properly, it allows chemists to isolate almost anything they can imagine. Witness a technique at the core of Professor Davis's laboratory experience.

Start examining various classes of organic compounds with alkanes, whose hydrocarbons consist entirely of hydrogen and carbon. How can a few simple carbon atoms lead to millions of possible alkane structures? How does structure affect their physical properties? And what curious role did they play in 19th-century whaling?

Turn now to nitrogen, which has played an important role in the chemistry of life since it began. Learn the chemistry of primary, secondary, and tertiary amines, the simplest of nitrogen-containing compounds. Also, consider imines (containing a pi-bond to nitrogen) and nitriles (where two pi bonds are present), including the simplest and most well-known nitrile: hydrogen cyanide.

Discover how solubility makes for an extremely effective tool for isolating non-volatile organic compounds through liquid-liquid and solid-liquid extractions (part of a larger phenomenon known as partitioning). As you delve into these processes, you'll learn one way to better understand extractions: making a perfect cup of tea.

Investigate substitution reactions: one of the fundamental mechanisms by which one compound becomes another. The simple molecules you've encountered so far can be altered in targeted ways and once you understand how these reactions work, Professor Davis says you've reached "a palpable threshold in the study of organic chemistry."

How can pi bonds change the chemistry of hydrocarbons? How did one of the greatest rivalries in chemistry lead to an understanding of trends in stability among regio- and stereoisomers with the same molecular formula? Why do terminal alkynes have such unusual acidity? Professor Davis has the answers to these and other questions.

Cover the second class of organic reaction: eliminations, the primary method for producing alkenes. As you'll learn, elimination reactions proceed with the production of a byproduct formed by the leaving group; in contrast to substitution reactions, they involve a significant increase in entropy because they make more molecules than they consume.
