A Claisen condensation between two different esters is called a crossed Claisen condensation. There are two main types of crossed Claisen that we will go over in this post. One is the reaction between esters, both having alpha hydrogens, and ... Read more

Organic Chemistry Acid-Base Chemistry Bronsted-Lowry Acid-Base Equilibrium In this lesson, I want to talk about the fundamentals of the acid-base equilibrium and how we use it within the scope of organic chemistry. But before we go into the details of the acid-base equilibrium itself, let’s review what a base and what an acid is according...
