Group theory 28: Groups of order 120, 168
This lecture is part of an online math course on group theory. It discusses some examples of groups of order 120 or 168: the binary icosahedral group, the symmetric group, and the symmetries of the Fano plane.

Group theory 20: Frobenius groups
This lecture is part of an online mathematics course on group theory. It gives several examples of Frobenius groups (permutation groups where any element fixing two points is the identity).

Abstract Algebra - 9.2 Factor Groups
Closely related to our study on normal subgroups, we now look at factor groups (aka quotient groups). These are groups created by partitioning a group according to a subgroup. We essentially divide the group by the subgroup, thus the name! Video Chapters: Intro 0:00 Recall a Normal Subgro

37. Proving the Configuration of Glucose and Synthesizing Two Unnatural Products
Freshman Organic Chemistry II (CHEM 125B) Modern spectroscopic tools show not only the constitution, configuration, and conformation of glucose but also how it interconverts between isomeric hemiketal pyranose rings. One of mankind's great accomplishments was determinining its constitut

27. Communicating Molecular Structure in Diagrams and Words
Freshman Organic Chemistry (CHEM 125) It is important that chemists agree on notation and nomenclature in order to communicate molecular constitution and configuration. It is best when a diagram is as faithful as possible to the 3-dimensional shape of a molecule, but the conventional Fisc

Symmetric Groups (Abstract Algebra)
Symmetric groups are some of the most essential types of finite groups. A symmetric group is the group of permutations on a set. The group of permutations on a set of n-elements is denoted S_n. Symmetric groups capture the history of abstract algebra, provide a wide range of examples in

Assigning R/S on Fischer Projections
We've learned about stereochemistry and also how to assign absolute configuration (R/S) to stereocenters using the Cahn-Ingold-Prelog convention. But some students are forced to learn all of this on dreaded Fischer projections. These are discussed in my biochemistry playlist, as they apply
