Calculating Oxidation Numbers in MCAT General Chemistry

Calculating Oxidation Numbers in MCAT General Chemistry

Oxidation numbers can be confusing, unless you think of it as charge (real or imaginary) associated with each specific atom in a complex molecule or polyatomic ion.     Calculating Oxidation Numbers Video 1 – Oxidation Numbers This video shows you how to find and calculate oxidation numbers when given simple and complex molecules or […]

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 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 […]

Aromaticity Practice Problems for Aromatic, Antiaromatic, Nonaromatic

aromatic antiaromatic nonaromatic practice questions

Aromaticity is one of the more exciting topics in organic chemistry! Partly because of it’s potential for easy points on your quiz/exam.. that is IF you truly understand, not merely memorize: when you know what to look for to identify aromatic, antiaromatic and non aromatic compounds. Start with the Aromaticity Review + Videos, then see how […]

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: […]
