Description
How do organic chemists actually prove the behavior of molecules and chemical structures you've learned about in the preceding lectures? The answer: spectroscopy, which entails the observation of the interaction between matter and light. In the first of several lectures on the topic, focus specifically on observations made with the UV-visible spectrum.

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.

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.
