Redox Pairs and Common Oxidizing and Reducing Agents

Redox Pairs and Common Oxidizing and Reducing Agents in MCAT General Chemistry by Leah4sci

Oxidation and reduction cannot happen on their own. When one atom loses electrons another atom has to gain these electrons. This video walks you through redox pairs using the mnemonic LEO the lion says GER to help you understand oxidizing/reducing agents. You’ll also learn how to recognize (rather than memorize) common oxidizing and reducing agents. […]

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: […]

Lithium Aluminum Hydride LiAlH4 Carbonyl Reduction Reaction and Mechanism

Lithium Aluminum Hydride (LiAlH4) Reduction Tutorial Video by Leah4sci

Lithium Aluminum Hydride LiAlH4 is the stronger ‘common’ carbonyl reducing agent. In addition to reducing aldehydes and ketones like NaBH4, LiAlH4 will also reduce carboxylic acids and carboxyl derivatives. The video below shows you a molecule and reaction overview followed by the reduction mechanisms for LiAlH4 with various carbonyl compounds. (Watch on YouTube: LiAlH4 Reduction. Click […]

Sodium Borohydride Carbonyl Reduction Reaction and Mechanism

Sodium Borohydride (NaBH4) Reduction Tutorial Video by Leah4sci

Sodium Borohydride NaBH4 is a common reducing reagent used with carbonyl compounds. NaBH4 is a weak reducing agent and will only reduce ketones and aldehyes. Watch for the explanation below including reaction, mechanism, and practice problems. (Watch on YouTube: NaBH4 Reduction.

Oxidation Reduction Organic Chemistry Practice Quiz

Oxidation and Reduction Organic Chemistry Practice Quiz

Oxidation and Reduction reactions will come up over and over in your organic chemistry course. Think you’ve mastered redox reactions and reagents? Try the practice quiz below then scroll down (end of the quiz) for the PDF solutions. Not fully confident with redox? Review the redox tutorial video series and follow along with the Orgo Redox […]

Birch Reduction Reaction and Mechanism

Birch Reduction Reaction and Mechanism Benzene and Substituted Rings Leah4sci

Aromatic compounds are considered very stable thus difficult to react. Birch Reduction is one example of an extreme reaction strong enough to break benzene’s aromaticity to form an non conjugated cyclohexadiene. This video breaks down the reaction and mechanism, followed by my trick for quickly identifying the product when EDG/EWG substituents are present. (Watch on YouTube: Birch […]

Oxidation and Reduction of Alkenes and Alkynes

Alkenes & Alkynes Oxidation Reduction and Oxidative Cleavage Leah Fisch

This video takes you through the various oxidation and reduction reactions you’ve covered back in alkene and alkyne reactions. In this video we differentiate between redox reactions vs reactions that add oxygen/hydrogen without a net reduction. This video also compares different types of oxidative cleavage reactions using Ozonolysis and KMnO4 for terminal and internal alkenes […]

Introduction to Oxidation Reduction Reactions in Organic Chemistry

Oxidation and Reduction in Organic Chemistry Tutorial Video Series

Oxidation and Reduction reactions in organic chemistry are very different than the redox concepts covered in general chemistry. This video shows you how the same gen-chem concepts apply, while helping you analyze it from a molecular and organic chemistry reaction perspective. This video covers the logic, definitions, and tricks to look out for when identifying […]

Orgo Oxidation Reduction Reactions Study Guide Cheat Sheet

oxidation reduction reactions cheat sheet preview

Oxidation and reduction reactions in organic chemistry can get very confusing very quickly due to the sheer volume of reaction types and chemical reagents involved. To help you keep track of these reactions and reagents I’ve put together the Oxidation/Reduction Study Guide Cheat Sheet Below.   This guide is the result of hours of work, […]

Alkyne Reactions Overview Cheat Sheet – Organic Chemistry

alkyne reactions cheat sheet summary for organic chemistry reactions

In response to the feedback for my alkene reaction cheat sheet I’ve compiled another organic chemistry reference sheet, this time for alkyne reactions. Do NOT simply use this guide to memorize reaction products. Instead use this guide as you study to ensure that you understand mechanisms and recognize reaction sequences. I spent nearly 2 hours […]
