From Crash Course.
The organic molecules that make up life on Earth are more than just the 2-D structures we’ve been drawing so far. Molecules have 3-D shapes that help us understand what they can do. In this episode of Crash Course Organic Chemistry, we’ll learn how orbital hybridization and valence bond theory can help us explain 3D molecular structures and about constitutional and geometric isomers.
