Alkyne Acid Catalyzed Hydration Reaction and Mechanism

Alkyne Hydration Reaction and Mechanism Leah4sci

Alkynes, like alkenes, can undergo acid-catalyzed hydration. However, since alkynes are slower to react under these conditions we prefer to use alternative reactions. This video walks you through the step by step reaction and mechanism including the final enol-keto tautomerization. (Watch on YouTube: Alkyne Hydration.

Acid Base Equilibrium Organic Chemistry Practice Questions

Acid Base Equilibrium Organic Chemistry Practice Questions by Leah Fisch

Ranking acids and bases are about more than just knowing which is stronger/weaker. This video walks you through a few practice questions where you’re asked to determine the position of equilibrium for acid-base reactions WITHOUT using PKA values. Instead, we’re using CARIO to determine which acids and bases are stronger and predicting the reaction direction […]

Aromatic Side Chain Oxidation to Carboxylic Acid

Aromatic Side Chain Oxidation to Carboxylic Acid by Leah4sci

Aromatic side chain oxidation is an interesting reaction. Benzene is not easily oxidized, nor is an alkane. However, when attached to a benzene ring the benzylic carbon is susceptible to a unique oxidation yielding a benzoic acid. This video walks you through the reaction including what to look out for along with multiple practice problems. […]

Tollens Reagent Silver Mirror Test for Aldehydes

Tollens Reagent Silver Mirror Test for Aldehydes by Leah4sci

 The Tollens Test for Aldehydes, also known as the Silver Mirror Test, is a great way to confirm if an unknown carbonyl is an aldehyde or not. This occurs by reacting the unknown carbonyl with Silver +1 which gets reduced to metallic silver (Ag 0) when the aldehyde is oxidized to a carboxylic acid. This […]

Naming Aromatic Compounds Part 2 Ortho Meta Para Substituents on Benzene

Naming Ortho Meta Para Substituents Benzene Tutorial Video by Leah4sci Orgo

In the previous video, Part 1 of the Aromatic Nomenclature, you saw how to name Benzene molecules using IUPAC and common nomenclature for a substituted benzene. This tutorial video below, Part 2, will walk you through the IUPAC rules for naming disubstituted benzene compounds using ortho meta and para. (Watch on YouTube: Aromatics 2. Click […]

Phenol Resonance and Acidity Organic Chemistry Video

Alcohols Resonance & Acidity of Phenol by Leah4sci

Phenol is a unique alcohol due to having a benzene ring and associated resonance. This video walks you through phenol resonance structures to help you understand how resonance impacts its acidity. Examples include comparing phenol to acetic acid as well as the impact of substituents on the ring like nitrophenol. (Watch on YouTube: Phenol Resonance/Acidity. Click […]

Acidity and Basicity of Alcohols Organic Chemistry Video

Alcohols Acidity and Basicity of Allcohols play

Alcohols are amphiprotic making them both acids and bases. This video shows you  how to rank acidity and basicity of alcohols using charge, electronegativity, resonance, and inductive effect with practice examples along the way. (Watch on YouTube: Acidity & Basicity. Click CC for Transcription.) Links & Resources Mentioned In This Video: Arrhenius, Bronsted-Lowry, and Lewis Acids […]

Alkyne Reduction Hydrogenation Reaction and Mechanism Video

Alkyne Reduction Hydrogenation Reaction and Mechanism Leah Fisch

Alkynes possess 2 pi bonds allowing for a full or partial reduction. This video walks you through the conditions required for all 3 reduction products including complete hydrogenation as well as the partial reduction to a cis or trans alkene. You’ll also learn the step by step mechanism for (radical) dissolving metal reduction. (Watch on YouTube: […]

Introduction to Alkyne Reactions in Organic Chemistry

Introduction to Alkyne Reactions in Organic Chemistry by Leah Fisch

Alkyne reactions typically mark the turning point between basic organic chemistry and this just got real! This video provides an introduction to what you can expect when studying alkyne reactions. From their basic chemistry and properties to the various alkyne reactions. (Watch on YouTube: Alkyne Intro. Click CC  for Transcription.) –> Watch Next Video: Alkyne Reduction – Hydrogenation […]

Acid Catalyzed Hydration of Alkenes Reaction and Mechanism

Acid Catalyzed Hydration of Alkenes 2 +L4S

Acid catalyzed hydration of alkenes involves replacing the pi bond on an alkene with a water molecule.  This is done by adding an alcohol to the more substituted carbon atom, and hydrogen to the less substituted carbon atom. This reaction follows Markovnikov’s rule and may undergo a carbocation rearrangement. If it is chiral, the product […]
