Khan Academy on a Stick


It's the liger of orbitals and essential to organic chemistry! In this tutorial, Sal discusses the hybridization of orbitals.

Dot structures

In this tutorial, Jay reminds you how to draw the dot structures of simple organic molecules.

Hybrid orbitals

In this tutorial, Jay goes over sp3, sp2, and sp hybridization.


What is the most important concept to understand in undergraduate organic chemistry? Of course, it's electronegativity! In this tutorial, Jay explains the concept of electronegativity and shows how it applies to polarity, intermolecular forces, and physical properties.
