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.
In this lecture,Professor Mike Christiansen, tells us that in addition, animal biochemistry contains many small molecule intermediates which assist in energy production through the Krebs cycle, and produces isoprene, the most common hydrocarbon i...
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.
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.
