Before you can really understand molecular and electronic geometries, you need to have a strong understand of why and how atomic hybridization occurs. The videos below are taken from my Organic Chemistry Basics tutorial series to help you make sense of sp3, sp2, and sp hybridization.
Once mastered you’ll find the MCAT Chemistry: Electronic and Molecular Geometry series easier to understand.
Start Here: Sp3 Hybridization
Then Continue Here: sp2 and sp Hybridization
Comfortable with Hybridization?
You’re now ready to study electronic and molecular geometries
