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 […]

Backpack Trick for Organic Chemistry Reactions

Backpack Trick for Organic Chemistry Reactions by Leah4sci

When it comes to organic chemistry reactions, many students focus on learning the EXACT steps by memorizing the SPECIFIC molecules presented in their books and lecture slides. Then, when something looks even slightly different on the exam, they panic! One such scenario: replacing water with alcohol in a reaction sequence – either as the attacking molecule or […]
