Solvent Effects on Sn1 and Sn2 Reactions
Sal reviews the Sn1 and Sn2 reactions with comparable reactants. He discusses which electrons are lost or gained and the conditions that make one or the other process favorable.
Khan Academy
E1 Reactions, Substitution and Elimination Reactions, Organic chemistry
This video builds upon the previous topic and explains how the elimination reaction between moderately electronegative molecules is controlled.
Khan Academy
Sn1 Reactions
A video on Sn1 reactions diagram water and 2-Bromo-2-Methylpropane. Sal discusses the possible behaviors of the valence electrons. He reviews the concepts of nucleophilicity and electronegativity and the speed of each reaction stage.
Khan Academy
Addition of Water (Acid-Catalyzed) Mechanism, Organic Chemistry
Sal starts this lecture by presenting the question as it might appear in a test or chemistry problem set. After reviewing the naming of a molecule and then drawing it to clarify the electron arrangement, he explains how to determine the...

Alcohol Properties, Alcohols, Ethers, Epoxides, Sulfides, Organic Chemistry
The properties of water, such as electronegativity, are related to its physical behavior. Water's boiling point, miscibility, and solubility are compared to those of other substances and related to van der Waals forces.
Khan Academy
Introduction to Reaction Mechanisms, Alkenes and Alkynes, Organic Chemistry
Starting with an example of how bromide might react with various alkenes, this lecture illustrates how valence electrons and electronegativity influence the likelihood of reactions.
