Organic Chemistry Acidity Practice Problem: Comparing Acidity of Protons on a Single Molecule

In this video I will explain how to determine what protons (H+) are more acidic in the same molecule. This is a common problem in organic chemistry and one you will have to address in your organic chemistry course. It is critical that an organic chemistry student is able to not only predict what protons on a molecule are acidic but why they are the most acidic. In this video I will demonstrate the steps that a student should use to explain the differences in pka (ka). pka = -log ka.

Enjoy these acidity practice problems! Success in Organic Chemistry is within your grasp!

In organic chemistry I (Intro to organic chemistry) it is important to be able to identify the acidic protons (hydrogens) and be able to predict how strong or weak the conjugate base will be. An important factor that effects the conjugate base is resonance. If a conjugate base resonances it is likely to be less basic and therefore more stable in water. Remember the stronger the acid the weaker the conjugate base. Strong acids have weak conjugate bases. Strong bases have weak conjugate acids. Acids and bases are important. I wish you all success in organic chemistry.

Being able to push arrows and draw resonance forms is a critical skill that you must learn to be successful in organic chemistry. Performing acidity practice problems will help you be successful in organic chemistry.

This video is part of a series called How to be Successful in Organic Chemistry. It this series I go over numerous problems that a student could expect to see in there organic chemistry 1 course. Doing organic chemistry practice problems will make you more successful in organic chemistry and biochemistry.

I recommend that you download the problem from the link below and attempt the problem yourself and use this video to correct your work.

Good Luck and Good Chemistry!
