San Diego Organic Chemistry Tutor Dr. The bonding orbital forms, when two atomic orbitals interact in the same phase ( constructive interaction). When orbitals aren't aligned properly, they don't interact “productively,” and hence there will be no phantom alkene with energy-stabilizing π-bond formation. So there are a bonding and anti bonding orbital for each sub orbital interaction. Molecular Orbital Theory vs Valence Bond Theory We know that molecules have different chemical and physical properties than the individual atoms which. When they interact out of phase (destructive interaction), anti bonding orbitals from. In both pyrrole and pyridine, an sp2 orbital contains the pair of electrons. Next this excitation is applied to the spin of the electron doublet (the aspect of the doublet which actually constitutes the quantum information) via a force called spin-orbit coupling. It is the interaction between the electron clouds of neighboring atoms that cause atoms to bond together. I think the usefulness of orbital theory in teaching general, undergrad organic chemistry is in helping to truly understand the mechanism. Aside from dangerous intermingling with the “true” convention (which does have deeper meaning, insofar as curved arrows represent orbital interactions), I feel like this approach is missing the forest for the trees. In pyrrole, an sp2 orbital contains the pair of electrons, while in pyridine, they are involved in the pi cloud. In effect, the interactions between electrons are 'shared' amongst the filled MOs. Instead, electrons must be viewed as swarming around the nucleus in clouds, called orbitals. If you're really clever, you've been thinking about the energy involved in “breaking bonds” vs. Joseph Lennox reveals "True Lies" behind the most common presentation of Newman Projection ethane energetics.
