Proton NMR Skills (Benzene Derivatives) - Part 1
 
18:45
In this video series I'll teach the techniques I use to interpret NMR spectra. If you watch the complete series, you'll have all the skills you need to interpret just about any NMR spectrum. In this video you'll learn how to handle disubstituted benzenes, aldehydes, ethers, and various other functional groups. If this video is too advanced for you, you may be missing some basic NMR theory. Check out this video series from my friend Frank Wong: https://www.youtube.com/watch?v=9orcRVTKcS0 Other Links!

26. Aromatic Substitution in Synthesis: Friedel-Crafts and Moses Gomberg
 
50:49
Freshman Organic Chemistry II (CHEM 125B) The Friedel-Crafts reaction creates new alkyl- or acyl-aromatic bonds, with or without cation rearrangement. Designing reaction sequences, especially those involving diazonium intermediates, so as to access a wide variety of substituted benzenes provides a good introduction to the challenges of synthetic organic chemistry. Aromatic rings with strong electron withdrawal can undergo nucleophilic aromatic substitution, which plays an important role in biochemistry. The special properties of phenyl-substituted alkanes, especially benzylic reactivity and steric hindrance, played an important role in the development of organic chemistry a century ago. 00:00 - Chapter 1.

1. Mechanism: How Energies and Kinetic Order Influence Reaction Rates
 
49:00
Freshman Organic Chemistry II (CHEM 125B) 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. It also treats the spectroscopy and synthesis of organic molecules. Reactions and their rates can be understood in terms of reaction-coordinate diagrams involving the passage of a set of atoms through the "transition state" on the potential-energy surface. Analysis of bond-dissociation energies suggests a chain mechanism for free-radical halogenation of alkanes. Experimental determination of kinetic order provides insight into complex reaction schemes, especially when one step is rate-limiting. 00:00 - Chapter 1. Energy and the reaction coordinate 07:31 - Chapter 2. Bond Strength and the Mechanism of Free-Radical Substitution 27:23 - Chapter 3.

Phenyl group
 
04:26
In organic chemistry, the phenyl group or phenyl ring is a cyclic group of atoms with the formula C6H5. Phenyl groups are closely related to benzene. Phenyl groups have six carbon atoms bonded together in a hexagonal planar ring, five of which are bonded to individual hydrogen atoms, with the remaining carbon bonded to a substituent. Phenyl groups are commonplace in organic chemistry. Although often depicted with alternating double and single bonds, phenyl groups are chemically aromatic and show nearly equal bond lengths between carbon atoms in the ring.

2. Peculiar Rate Laws, Bond Dissociation Energies, and Relative Reactivities
 
48:14
Freshman Organic Chemistry II (CHEM 125B) Curious kinetic orders can be mechanistically informative. Fractional kinetic orders suggest dissociation of a dominant aggregate to give a smaller reactive species. An apparent negative kinetic order, due to competition with a second-order process, leads to spontaneous deracemization of chiral crystals. Changes in bond dissociation energies can be due to differences in bonds or in radicals. Although it is often said that the order of alkyl radical stability is tertiary, secondary, primary, careful analysis suggests that the order of bond dissociation energies may be due to differences in the alkanes rather than in the radicals. Hammond helped organic chemists begin to think systematically about predicting relative reaction rates by suggesting that the transition states of more exothermic reactions should lie closer to the starting materials in structure and energy. 00:00 - Chapter 1.
