- Students who have fallen behind in understanding basic chirality concepts
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning about chemistry (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about chirality
- Students who struggle to understand their teachers
- Students who attend schools without extra chemistry learning resources
How It Works:

Students Will Review:
This chapter helps students review the concepts in a chirality unit of a standard chemistry course. Topics include:
- Chiral ions and molecules
- The differences between a chiral center and stereocenter
- Enantiomers vs. diastereomers
- Chiral vs. enantiomers
- Racemic mixture resolution
- Cahn-Infold-Prelog priority rules
- Enantiomeric excess
- Polymer tacticity
- Asymmetric induction factors, methods, rules and models
- Ray-Dutt twist and Bailar twist pathways
- Enantioselective synthesis
1. Chiral Molecules & Ions: Definition, Identification & Examples
In chemistry we often refer to chiral molecules. In this lesson we will learn what a chiral molecule is and how to identify a chiral molecule and chiral centers.
2. Stereocenter vs. Chiral Center
In this lesson, you will learn about stereocenters and chiral centers in molecules. The similarities and differences will be discussed in addition to some real-world implications.
3. What is the Difference Between Enantiomers & Diastereomers?
Enantiomers and diastereomers are types of stereoisomers. In this lesson we will learn what the difference is between these types of stereoisomers and how to differentiate between them.
4. Difference Between Chiral & Enantiomers
Since we can even use the word chiral in the very definitions of enantiomers, it can get confusing to differentiate the two terms. Let's learn what the difference between chiral and enantiomers is, and how to calculate the number of stereoisomers.
5. Cahn-Ingold-Prelog Priority Rules in Chemistry
The goal of this lesson is to understand the Cahn-Ingold-Prelog priority rules in chemistry and how these rules are used to prioritize groups of atoms bonded to a stereocenter in a molecule.
6. Enantiomeric Excess: Definition, Calculation & Examples
Sometimes we need to know how pure a mixture of two enantiomers is. In this lesson we will learn how to do this by calculating the enantiomeric excess.
7. Asymmetric Induction: Chelation, Non-Chelation, Cram-Reetz & Evans Models
What dictates the formation of one product over another in a reaction? In this lesson, we will study the stereochemistry concept of asymmetric induction by examining chelation, non-chelation, the Cram-Reetz, and the Evans models to see how one stereoisomer can be preferentially formed over another.
8. Racemization in Organic Chemistry: Definition, Mechanism & Example
How can you go from one, pure enantiomer to two? This lesson covers racemization reactions, their mechanism, and go over some specific examples involving amino acids and an alkyl halide.
