Summary
The discussion centers on the E2 reaction mechanism in cyclic systems, particularly focusing on the importance of the anti-conformation between the proton being extracted and the leaving group. The speaker explains that for an alkene product to form, the proton must be positioned 180 degrees opposite to the leaving group, which is crucial for the lateral overlap of unhybridized p orbitals necessary for pi bond formation.
In cyclic systems, the challenge arises due to the inability to rotate bonds freely as in linear systems. The speaker illustrates this with a chair conformation, emphasizing that both the leaving group and the proton must occupy axial positions to facilitate elimination. This requirement limits the available protons for elimination, as only those in axial positions on beta carbons can participate, making the stereochemistry of the cyclic structure critical for the reaction's success.

Didn't we already learn E2? Not so fast, when we are looking at E2 on cyclohexane it's a slightly different kettle of fish.

More from Professor Dave Explains
Anthony Fauci is a horrible demon man who eats babies and should be in jail! That's what I've been hearing from most of the public, anyway. Why are they saying that, though? What did he really do? As it turns out, he upheld real science in the face of state-sanctioned pseudoscience all throughout a pandemic that killed millions of people. For defying the state, his reward has been the most monumental smear campaign of a public servant in recent history. SARS-CoV-2 did not leak from a lab, Fauci never did anything but make science-based recommendations to save as many lives as possible, and if you didn't know that, you fell for propaganda from the government.

Finally! After talking about atoms and molecules in chemistry, big molecules in biochemistry, and all the parts of the cell in this biology series, we are finally ready to look at entire living organisms! But we have to start with the simplest ones on the planet, and that is undoubtedly bacteria. We went over many aspects of bacterial structure when we talked about prokaryotic cells, but now let's learn about the types of bacteria, and some of the things that they do.Watch the whole Biology/Genetics playlist: http://bit.ly/ProfDaveBioGeneral Chemistry Tutorials: http://bit.ly/ProfDaveGenChemOrganic Chemistry Tutorials: http://bit.ly/ProfDaveOrgChemBiochemistry Tutorials: http://bit.ly/ProfDaveBiochemAnatomy & Physiology Tutorials: http://bit.ly/ProfDaveAnatPhysBiopsychology Tutorials: http://bit.ly/ProfDaveBiopsychMicrobiology/Infectious Diseases Tutorials: http://bit.ly/ProfDaveMicrobioPharmacology Tutorials: http://bit.ly/ProfDavePharmaHistory of Drugs Videos: http://bit.ly/ProfDaveHistoryDrugsEMAIL► [email protected]► http://patreon.com/ProfessorDaveExplainsCheck out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!Amazon: https://amzn.to/2HtNpVHBookshop: https://bit.ly/39cKADMBarnes and Noble: https://bit.ly/3pUjmrn Book Depository: http://bit.ly/3aOVDlT Learn more about your ad choices.

To get started with Deuterostomia, we will look at phylum Hemichordata. These organisms are known as acorn worms, and they share some but not all of the chordate characteristics. There are fewer than 200 species in this phylum, so let's get a closer look!Script by Ryan HelcoskiWatch the whole Zoology playlist: http://bit.ly/ProfDaveZooGeneral Chemistry Tutorials: http://bit.ly/ProfDaveGenChemOrganic Chemistry Tutorials: http://bit.ly/ProfDaveOrgChemBiochemistry Tutorials: http://bit.ly/ProfDaveBiochemBiology Tutorials: http://bit.ly/ProfDaveBioAnatomy & Physiology Tutorials: http://bit.ly/ProfDaveAnatPhysMicrobiology Tutorials: http://bit.ly/ProfDaveMicrobioBotany Tutorials: http://bit.ly/ProfDaveBotanyEMAIL► [email protected]► http://patreon.com/ProfessorDaveExplainsCheck out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!Amazon: https://amzn.to/2HtNpVHBookshop: https://bit.ly/39cKADMBarnes and Noble: https://bit.ly/3pUjmrn Book Depository: http://bit.ly/3aOVDlT Learn more about your ad choices.

Up until this point we have been learning everything in the active voice. This would be something llike: "The dog chewed the bone". But there is also the passive voice, which would turn that sentence into "The bone was chewed by the dog." This is used quite a bit in Latin for various reasons, so we need to know how to use it!Script by Patrizia Farina, Professor of Italian at Western Connecticut State University and Purchase College.Watch the whole Latin playlist: http://bit.ly/ProfDaveLatinItalian Tutorials: http://bit.ly/ProfDaveItalianAmerican History Tutorials: http://bit.ly/ProfDaveAmericanHistoryPhilosophy Tutorials: http://bit.ly/ProfDavePhiloClassical Physics Tutorials: http://bit.ly/ProfDavePhysics1Modern Physics Tutorials: http://bit.ly/ProfDavePhysics2General Chemistry Tutorials: http://bit.ly/ProfDaveGenChemOrganic Chemistry Tutorials: http://bit.ly/ProfDaveOrgChemBiochemistry Tutorials: http://bit.ly/ProfDaveBiochemBiology Tutorials: http://bit.ly/ProfDaveBioEMAIL► [email protected]► http://patreon.com/ProfessorDaveExplainsCheck out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!Amazon: https://amzn.to/2HtNpVHBookshop: https://bit.ly/39cKADMBarnes and Noble: https://bit.ly/3pUjmrn Book Depository: http://bit.ly/3aOVDlT Learn more about your ad choices.
