Document Summary
Most polyatomic anions have resonance structures: average formal charge for an atom: Bond order: single (1), double (2), triple (3: average bond order: , the terminal bonds are on 2 oxygens; one double bond and one. 2- is bigger, so it has a larger terminal bond order. Molecular shape: vsepr (valence shell electron pair repulsion) theory, aka gillespie-nyholm theory. [ron gillespie, mcmaster chemistry!: the one who first performed this theory, electron pairs repel one another, repulsion decreases in this order: Bonded pair-bonded pair: *note*: double bonds occupy slightly more space than a lone pair. 2 electron pairs: electron pair geometry - linear. 2 electron pairs: electron pair geometry - trigonal planar, lone pair of electrons also occupies space; which makes it a little bit less than. Dipole review: vectors from center of atom to the terminal atoms when added together all cancel out; then the atom has no dipole (all the terminal atoms are the same; ex.
