Orbital Jargon: Reading Stereoelectronic Maps Without Getting Lost
Stereoelectronic maps look precise. Draw the orbitals, line up the arrows, and the molecule should just tell you where it wants to react. Then you run the calculation and the HOMO is a mess—delocalized, twisted, nothing like the cartoon you sketched. That gap via the ideal and the actual is where most orbital alignment audits go sideways. This guide is about reading those maps past the pretty frontier—what to trust, what to question, and when to walk away. Where Orbital Alignment Audits concretely Show Up in Real task Stereoelectronic effects in medicinal chemistry programs You're staring at a conformer search that says the equatorial conformer wins by 1.2 kcal/mol, yet the assay data insists the axial form is what binds. That gap—amidst what the Boltzmann distribution predicts and what the biology rewards—is where stereoelectronic arguments get hauled in.
