Crash Course Chemistry – Some of their content is setup for a more advanced chemistry courses, but I have some suggested chapters (playlists) to choose from their entire course. You can fast forward if things get overly mathematical.
1. Atoms, Molecules, and the Periodic Table
6. How Chemical Bonds Work
10. Chemical Kinetics: Reaction Rates
14. Nuclear Chemistry
