Stereoisomerism: Unlocking the Secrets of Molecular Twins
Stereoisomerism refers to isomers that have the same molecular formula and connectivity but differ in the three-dimensional arrangement of their atoms. This type of isomerism includes both geometrical isomers and optical isomers....

Allenes and Optical Activity: A Surprising Twist!
Allenes are compounds with a unique structure characterized by two adjacent double bonds (C=C=C). Despite having no traditional chiral centers, certain substituted allenes can exhibit chirality and optical activity due to their rigid,...

Chemical Filtration
We look at how chemical filtration can be used to remove contaminants from water. Potassium permanganate is used as the contaminant. First, we try to remove it using physical filtration, with filter paper and a funnel. This does not...

Practice Problem: IUPAC Nomenclature and Stereochemistry
For this one we will have to be able to interpret IUPAC nomenclature to draw molecular structure, including absolute configuration using the Cahn-Ingold-Prelog convention.

Radical Reactions Hammonds Postulate - Crash Course Organic Chemistry
Throughout this series we’ve mostly talked about pairs of electrons, but electrons don’t always have a buddy. An atom or group of atoms with a single unpaired electron is called a radical. In this episode of Crash Course Organic...
