WebLecture: Molecular Orbitals

Kotz and Triechel, Chemistry and Chemical Reactivity Chapter 9: Section 3.

9.3 The Molecular Orbital theory views electrons as a resource for the whole molecule rather than dedicated to individual bonds between specific atoms. Instead of starting with bonds and looking at the electrons in them, we start with all available electrons and build the possible bonds. This theory allows us to account for molecular relationships that valence theory doesn't explain very well.
