Video-lecture with most views in organic chemistry
Dr. David Van explains the concepts of organic chemistry very deeply The synthesis proceeds by utilizing the reactivity of the functional groups in the molecule.Lecture 30 of 39
Measuring Bond Energies, Diatomic Bond Dissociation Energy from Spectroscopy - Freshman Organic Chemistry - Barney Ellison - Lecture 32 of 38
Spectroscopic determination of bond dissociation energies is relatively straightforward for many diatomic molecules, but for polyatomic molecules it requires merging the results from a variety of challenging experiments.
Mechanism, How Energies and Kinetic Order Influence Reaction Rates - Freshman Organic Chemistry - Michael McBride - Lecture 1 of 38
This second semester of Freshman Organic Chemistry builds on the first semester's treatment of molecular structure and energy* to discuss how reaction mechanisms have been discovered and understood.
Solvent, Leaving Group, Bridgehead Substitution, and Pentavalent Carbon - Freshman Organic Chemistry - Michael McBride - Lecture 8 of 38
The nature of nucleophiles and leaving groups has strong influence on the rate of SN2 reactions. Generally a good nucleophile or strong base is a poor leaving group, but hydrogen-bonding solvents can alter nucleophile reactivity.
Rate and Selectivity in Radical Chain Reactions, Reactivity Selectivity Principle - Freshman Organic Chemistry - Michael McBride - Lecture 3 of 38
The reactivity-selectivity principle explains why bromine atoms are more selective that chlorine atoms in abstracting hydrogen atoms from carbon. A free-radical mechanism for adding HBr to alkenes explains its anti-Markovnikov regiospecificity. Ca...
