The key to mastering alcohol reactions is understanding WHY they react as they do. What about the OH functional group makes it want to attack or get attacked, as you will learn in later mechanisms? This video will give you a solid foundation to help you prepare to master the more advanced reactions starting with […]

Acid Catalyzed Hydration of Alkenes Reaction and Mechanism
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 […]
Hydroboration Oxidation of Alkenes
Hydroboration-oxidation is yet another alcohol yielding alkene reaction. However this reaction results in an alcohol adding to the less substituted carbon for an anti-Markovnikov product. The video below helps you understand the reactivity of Boron as well as the hydroboration and oxidation steps of the reaction mechanism. Watch this video on YouTube or read the […]
Backpack Trick for Organic Chemistry Reactions
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 […]
Diels Alder Reaction Mechanism and Product Trick Vid 1
The diels alder reaction can come in many forms. You’ll be faced with confusing reactants and complex products. The first step to mastering this reaction is to truly understand the diels alder mechanism and pattern. This video breaks down the reaction then shows you my trick for quickly identifying products from any reactant, and the […]
Diels Alder Reaction for Cyclic Reactants and Bicyclo Products
The Diels Alder reaction will appear in many different forms on your organic chemistry exams. My favorite is when you’re given a cyclic starting diene, or perhaps a bicyclic product and asked to find the starting diene and dienophile. In this video I show you how to tackle these problems using my trick from video 1. […]
Alkoxymercuration Demercuration Reduction of Alkenes
Alkoxymercuration-Demercuration Reduction is a tricky mechanism for organic chemistry students. Not because it’s any more difficult than oxymercuration, but simply because students tend to overlook the alcohol reagent and miss the alkyl group in the product. The video below helps you understand the similarities and differences between oxymercuration and alkoxymercuration of alkenes. The video also […]
Oxymercuration-Demercuration Alkene Reaction Mechanism
Oxymercuration-Demercuration, also referred to as oxymercuration-reduction is slightly more confusing than that average alkene reaction. I think it’s a combination of the extra steps, involvement of mercury, and the mysterious reduction by sodium borohydride. But don’t let this confuse you. The video below takes you through the entire reaction mechanism with step by step explanations […]
Polarimetry in Optical Activity
Polarimetry is the key to understanding chiral molecules in terms of optical activity. This video goes behind the scenes of the polarimeter to help you understand what plane polarized light has to do with chiral molecules. Part 1 (of 3) in this mini series explains + D and – L, dextrorotatory and levorotatory, and their (lack […]
SN1 Reaction Mechanism Examples of Unimolecular Substitution Part 2
SN1 SN2 E1 Series: Video 16 Unimolecular Nucleophilic Substitution video 2 of 3 – this video takes you through additional SN1 reaction mechanism examples. As you work through this video pay attention to the logic, concepts, and especially patterns. Doing so will help you understand when to choose SN1 while avoiding confusing memorization (Watch on […]
