The following videos serve as aids for more effective class preparation when you read the chapter material and work the assigned problems before each class.
- Putting it all Together (M4V)
This video details the mechanism of one of the most common methods of ester preparation, from the acid-catalyzed reaction of an alcohol and a carboxylic acid.
- Violating the Octet Rule (M4V)
Sometimes atoms can violate the octet rule (by having either more or less than eight electrons around themselves) when designing Lewis Structures; this video explains why and how this can be used to generate structures with the lowest formal charges.
- Lewis Structures and Formal Charges (M4V)
This video shows the rules used to draw Lewis Structures and calculate formal charges, through the use of several example molecules/ions.
- Pushing Electrons (M4V)
This video shows the basics behind how electrons move in chemical reactions and the principles behind how to push them in reaction mechanisms.
- Resonance (M4V)
One of the most important concepts to master in the study of organic chemistry, an understanding of the principles behind resonance and what it means in terms of stability is explained here.
- Naming Alkanes Basics (M4V)
Illustrates the basics behind the IUPAC system of nomenclature for alkanes, through the use of several examples.
- More Naming Alkanes (M4V)
How to name more complex, polysubstituted alkanes is covered in this video, through the use of three example structures.
- Naming Cycloalkanes (M4V)
This video provides the rules for naming cyclic alkanes and illustrates these rules through the use of several example molecules.
- Ring Flips Diaxial Interaction (M4V)
How to draw chair conformations for substituted cyclohexanes is covered in this video, as well as the distinction between axial and equatorial groups and how to draw them. Also covered are 1,3-diaxial interactions, their effect on a molecule's stability and how to recognize when they are present in a molecule.
- Overview Alkenes Addition (M4V)
Alkene chemistry is dominated by addition reactions across the pair bond, and this video illustrates the principles behind how this addition occurs with small molecules. Several examples are used to illustrate the concept.
- Markovnikov's Rule (M4V)
Addition of small molecules across unsymmetrical alkenes gives particular products, via the most stable carbocation intermediate. Markovnikov's rule can be used to predict products from these reactions, and this video outlines the basics of how to apply Markovnikov's rule.
- Carbocation Rearrangements (M4V)
This video details the situations in which carbocations can rearrange to increase their stability, and the pathways by which they rearrange (hydride and alkyl shifts).
- Alkene Halogenation (M4V)
This video outlines the mechanism by which halogens add across double bonds to give anti-addition products by halonium ion intermediates.
- Halohydrin Formation (M4V)
This video details the mechanism by which halogens add across alkenes in the presence of water, and the structure of the halohydrin products that form.
- Hydroboration Oxidation (M4V)
The single addition reaction that results in non-markovnikov alcohol formation from an alkene; this video illustrates the reaction through the use of several examples.
- MS and IR (M4V)
This video illustrates basics of the techniques of Infra-Red (IR) spectroscopy and Mass Spectrometry (MS), fundamentals of how to interpret their spectra, and use of this data in structure determination.
- NMR (M4V)
This video illustrates basics of the technique of Nuclear Magnetic Spectroscopy (NMR), fundamentals of how to interpret each of 1H, 13C and 13C DEPT spectra, and how this data can aid in structure determination.
