Why does the MO diagram for p shells change starting form the element oxygen? For B, C, and N, the bonds form starting with pi bonds with the lowest energy and then moving up to the sigma bond. Starting from oxygen and beyond, however, it returns to the more familiar phenomenon of forming sigma bond...

Re: Rusty on High School Chem [ENDORSED]

I'm a bit different from you in that I was an IB Chemistry HL student. What helped me most through my IB career were tutoring websites such as Khan Academy and general discussion forums. I never actually had a real tutor in high school and mostly self studied, and that will be a big part of college ...
