Calorimetry: This tutorial discusses the theory behind calorimetry and the differences between coffee cup calorimetry and bomb calorimetry. (Runtime = 10:05) Phase Diagrams: Have you ever wondered what was involved in a phase diagram and how to interpret it? This PreLecture addresses the important skill of interpreting data about phase changes and relating it to heating and cooling curves. (Runtime = 8:33) Periodic Trends: Most of the periodic trends that are observed can be explained by two main ideas: electron shielding and nuclear pull. This pre-lecture explains these two concepts and then shows how they can be applied to explain the trends in atomic radius. (Runtime = 9:52) Lewis Structures: This pre-lecture is a basic introduction to drawing Lewis structures of both ionic and molecular compounds. It illustrates simple strategies for drawing basic Lewis structures. (Runtime = 17:19) |

VSEPR: This tutorial discusses the concept of hybridization and explains how hybridized orbitals are the building blocks of organic chemistry. Using hybridization, VSEPR, and bonding theory, the tutorial shows how the shapes of molecules can easily be predicted. (Runtime = 29:18) Resonance Structures: Resonance is a concept that is frequently used in ochem to explain chemical reactivity. This tutorial provides the basics of drawing resonance structures. (Runtime = 14:07) Acidity and Basicity: This tutorial provides an approach for qualitatively determining the relative acidity or basicity of an acid or base. (Runtime = 19:29) Nomenclature of Alkanes: Your ability to name organic compounds (for the entire course) is grounded in your understanding of how to name alkanes. This tutorial covers the basics of alkane nomenclature. (Runtime = 20:51) Nomenclature of Functionalized Molecules: This tutorial builds upon the previous one on naming alkanes by presenting a general approach to naming a few other classes of organic molecules. (Runtime = 13:20) Conformational Analysis: This tutorial introduces the concept of conformations of molecules, and how we can discuss the different shapes that molecules can assume using a type of drawing known as a Newman Projection. (Runtime = 18:58) Mechanisms of Reactions: Mechanisms are drawings that show the movement of electrons in reactions. This tutorial introduces this method of presenting the way reactions proceed. (Runtime = 9:24) Visualizing in 3-D: This tutorial provides some practice in manipulating molecules in 3-D space. It is intended to help those who may have difficulty visualizing in 3-D. (Runtime = 10:03) Chirality: This tutorial presents the idea that many objects, including molecules, have left and right handed versions. (Runtime = 5:47) Synthesis: This tutorial discusses how to approach synthesis problems using a technique known as retrosynthetic analysis. (Runtime = 17:07) Degrees of Unsaturation: This tutorial shows you how, just based on a molecular formula, you can quickly and easily propose possibilities for a molecule's structure. This technique will come in handy when doing spectroscopy problems. (Runtime = 14:21) Spectroscopy, part 1 of 4 In this first tutorial of a three part series, you are introduced to the 3 most common types of spectroscopy encountered in an organic chemistry course. (Runtime = 11:09) Spectroscopy, part 2 of 4 This 2nd part of the series shows you how to approach combined spectral problems. Specifically, you will be guided through the solution of two problems in which you are given a molecular formula, a mass spec., and an IR spectrum for each. (Runtime = 13:24) Spectroscopy, part 3 of 4 This tutorial covers 13C NMR spectroscopy. It's purpose is to act as a summary of how you can use 13C NMR to solve structure problems. It is NOT meant to be an introduction to the topic, but rather a guide for you to refer to AFTER you have read the text or attended the lecture on the topic. (Runtime = 18:47) Spectroscopy, part 4 of 4 This tutorial covers 1H NMR spectroscopy. It's purpose is to act as a summary of how you can use 1H NMR to solve structure problems. It is NOT meant to be an introduction to the topic, but rather a guide for you to refer to AFTER you have read the text or attended the lecture on the topic. (Runtime = 22:40) Nucleophilic Acyl Substitution Nucleophilic acyl substitution is a reaction that is ubiquitous to carboxylic acid derivatives. This tutorial shows how these compounds undergo a common mechanism regardless of the starting material or nucleophile. (Runtime = 11:14) The Aldol Reaction The aldol reaction is the reaction of an enolate of a ketone or aldehyde with the carbonyl carbon of another ketone or aldehyde. It is one of the most useful ways to form a carbon-carbon bond. This tutorial covers the basics of the reaction. (Runtime = 25:01) |
