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: […]
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 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 […]
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 […]
During synthesis, protecting a reactant is a game changer. Without this ability, arriving at the correct product will be painful and sometimes near impossible. Utilizing a cyclic acetal protecting group is one of the handiest tools we can have in our synthesis arsenals. This video will so you a step-by-step detailed mechanism along with tips for redrawing, […]
Acetal and Hemiacetal mechanisms can be long, but when you UNDERSTAND each step you’ll be saved from a big headache and trouble from merely memorizing. This video walks you step-by-step through the acid catalyzed acetal formation reaction mechanism! You’ll see special attention on the acetal, hemiacetals, ketals, and hemiketals in the mechanism as well as […]

Specific Rotation calculations are a useful tool in optical activity. This video will help you understand the factors influencing specific rotation such as observed rotation, g/mL, path-length, wavelength, and temperature. You will see a detailed breakdown of the equation along with a few examples to follow along. (Watch on YouTube: Optics 2. Click CC for video transcription.) <– […]
The key to understanding physical properties of alcohol, including hydrogen bonding solubility and boiling point is to understand the structure and charge distribution within the alcohol functional group. This video will show you the behind-the-scenes intermolecular forces at work that affect alcohol’s ability to hydrogen bond for solubility in water, miscibility, and boiling point trends. You’ll […]
