Backpack Trick for Organic Chemistry Reactions

Backpack Trick for Organic Chemistry Reactions by Leah4sci

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 […]

Orgo Mechanisms with Common Arrow Patterns

Organic Chemistry Mechanisms Part 3 in Video Tutorial Series by Leah4Sci

Organic chemistry is all about mechanisms. And while the sheer volume may feel overwhelming, they all boil down to a few simple types of mechanism steps. In Part 1 and Part 2 we looked at the four common mechanism types: Nucleophilic attack, Loss of Leaving Group, Proton transfer and Rearrangements. In this video we’ll look at TWO […]

Proton Transfer and Rearrangement Mechanisms in Organic Chemistry

Organic Chemistry Mechanisms Part 2 in Video Tutorial Series by Leah4Sci

Proton transfer and rearrangements are 2 more common mechanism patterns you will face in organic chemistry. This is in addition to Nucleophilic attack and Loss of Leaving Group discussed in Mechanism Video Part 1. You’ll see multiple proton transfer examples in action including turning a bad leaving group into a good leaving group! Rearrangement mechanism are broken down for […]

Intro to Orgo Mechanisms Nucleophilic Attack and Loss of Leaving Group

Mechanisms Part 1 in Organic Chemistry Tutorial Video Series by Leah4Sci

Organic chemistry is all about the reaction mechanisms and moving arrows. Video 1 in this Mechanism series will help you understand what the heck these mechanisms are all about. We’ll start with a quick overview of what to look for, how to write the mechanisms, reaction arrows, and more. Then we’ll look at the first […]

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 […]

Halohydrin Formation – Alkene Reaction Mechanism

halohydrin formation reaction mechanism

Reaction Overview: The Halohydrin formation reaction involves breaking a pi bond and creating a halohydrin in its place. Halo = halogen and Hydrin = OH. This reaction takes place in water and yields an anti-addition reaction which follows Markovnikov’s rule. Reaction Summary Nucleophilic pi bond attacks halogen molecule, pi bond breaks in the process Halogen lone […]
