Organic Reactions and Pharmaceuticals, Lec 17, Chemistry 14D, UCLA


Course Description: Chemistry 14D: Organic Reactions and Pharmaceuticals is a class that provides an in depth analysis of organic reactions, nucleophilic and electrophilic substitutions and additions; electrophilic aromatic substitutions, carbonyl reactions, catalysis, molecular basis of drug action, and organic chemistry of pharmaceuticals. About the Professor: Professor Hardinger has been a faculty member in the UCLA Department of Chemistry and Biochemistry since 1997. His professional career began at Drexel University in Philadelphia, which afforded a BS in Chemistry in 1982. He then moved to Purdue University, and earned a PhD in Organic Chemistry in 1988. Two subsequent years as a postdoctoral scholar at Renssalear Polytechnic Institute were followed by appointment in 1990 as assistant professor at California State University. In 1997 he achieved the “forbidden transition” and moved to UCLA as Lecturer followed by promotion to Senior Lecturer in 2004. At UCLA his main teaching interests have been introductory organic chemistry courses in the physical science majors series as well as the life science majors series. His professional interests include development of new teaching tools and methods, both in print and electronic media. An introductory organic chemistry textbook (Organic Chemistry – A Thinking Student’s Approach) is currently in development.

Chemistry: Precision and Accuracy


www.mindbites.com In this lesson, Prof. Yee discusses precision and accuracy in measurements. He explains that all measurements will have a degree of uncertainty due to instrumentation, and the range of uncertainty will appear in the last digit of the measurement. You want to have measurements that are both precise and accurate. Precision is the reproducibility of the measurement of a quantity and is tied to the concept of random error. Prof. Yee uses a ruler as an example of precision. Accuracy refers to how close a measurement is to a hypothetical true value. It is possible for a measurement to be precise but not accurate if there is a systematic error. Systematic error is an error inherent to the measurement of a value, such as a clock that is consistently 5 minutes fast. Finally, Prof. Yee explains the relationship between precision and accuracy using a game of darts. Taught by Professor Yee, this lesson was selected from a broader, comprehensive course, Chemistry. This course and others are available from Thinkwell, Inc. The full course can be found at www.thinkwell.com The full course covers atoms, molecules and ions, stoichiometry, reactions in aqueous solutions, gases, thermochemistry, Modern Atomic Theory, electron configurations, periodicity, chemical bonding, molecular geometry, bonding theory, oxidation-reduction reactions, condensed phases, solution properties, kinetics, acids and bases, organic reactions, thermodynamics, nuclear chemistry, metals, nonmetals

Chemistry: Naming Cations & Understanding Nomenclature


www.mindbites.com Naming chemical compounds can be tricky, and requires a little bit of knowledge about the trends and naming conventions. First, Professor Harman explains that how you name a compound will depend on the type of compound – whether it is an ion, molecular compound, acid, or base. For ions, the way you name the ion will depend on whether the compound is a cation or anion and whether or not it is monatomic, polyatomic, or a transition metal. Anions follow slightly more difficult naming conventions. Molecular compounds use Greek prefixes and will always start with the element furthest from Fluorine. Some molecular compounds have common names (such as water), and these are always used. Bases are simply named like ionic materials. Acids are named based on the suffix of the anion they are derived from. If the anion ends in -ate, the acid uses an -ic suffix. If the anion ends in -ite, the acid uses an -ous suffix.
