CH 301 Study Guide - Midterm Guide: Antibonding Molecular Orbital, Stick Figure, Diamagnetism
Document Summary
Molecular bond theory- focused on the molecule as a whole instead of the central atom. yields orbitals and energies just like quantum calculations. How the electrons are arranged around the model, arranged in order of lowest to highest energies- molecule anti-bonding(* or *)- destructive- destabilizes bonding (or )- constructive- always lower energy. Lumo- lowest unoccupied molecular orbital, usually the next step above homo. Paramagnetic- attracted by magnets- some unpaired electrons (ex: o2) Reasoning behind the differences between the next 2 set ups. This steps usually shows whether or not there are any double/triple bonds: use the number of available electrons (a, from #2) to distribute electrons. Start by counting the electrons being used in the bonds (each line is 2 electrons, cuz they are shared). Fill up each of the outer atoms by completing the octet, unless it"s hydrogen: with any electrons left over after #4, dump them on the central atom .
