Basicity of Amines And pKaH
Quantifying The Basicity Of Amines, Using “The pKa Of The Conjugate Acid”, a.k.a. “pKaH” How do you measure the basicity of an amine? Case in point:

Acid-Base Reactions Of Alcohols Alcohols are mild acids. Typical aliphatic (i.e. “alkyl”) alcohols such as ethanol, isopropanol, and t-butanol have a pKa of about 16-18, making

Today we’ll talk about an incredibly important skill that might take some time to grasp but pays tremendous dividends. We’ll go through the exact details of how to use a pKa table. Understanding the proper use of a pKa table will give you the ability to recognize which acid-base reactions will happen and which will not. This will come up a lot as you progress through Org 1 and Org 2. It might be helpful to go back and review some of the factors that affect acidity that were talked about earlier.
