A Simple Approach to Retrosynthesis in Organic Chemistry

Organic Chemistry Retrosynthesis Tutorial by Leah4sci

In Organic Chemistry, synthesis and retrosynthesis go hand in hand. While there isn’t a clear distinction, I like to think of synthesis as forward thinking and retrosynthesis as the reverse. Synthesis is a topic that is typically introduced in Organic Chemistry 1, right after studying alkyne reactions. You’ll be utilizing it again and again as […]

How to Tackle Organic Chemistry Synthesis Questions

How to tackle organic chemistry synthesis

Organic chemistry may cover many concepts and topics, but it’s all about the reactions and mechanisms. It’s not so scary at first, think about the simple acid/base deprotonation, an alkene reaction here, another there. Before you know it, you’re drowning in dozens upon dozens of reactions! You’re asked to ‘memorize’ each one, to know what every […]

Diels Alder Reaction Mechanism and Product Trick Vid 1

Diels Alder Reaction Mechanism Video by Leah Fisch

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 […]

Hydroboration Oxidation of Alkenes

hydroboration oxidation alkene reaction mechanism tutorial video

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 […]

Alkoxymercuration Demercuration Reduction of Alkenes

Alkoxymercuration Demercuration Reduction Alkene Reaction Mechanism Leah4sci

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 […]
