Terms | Definitions |
|---|---|
 resonance hybrid | composite of all possible resonance structures |
| delocalized | when e- pairs in resonance structures are drawn in diff locations |
| hybridization | combination of two/+ atomic orbitals to form the same # of hybrid orbitals, each the same shape and energy |
| increase in % s character | increase acidity, increase in bond strength, decrease bond length |
| Bronsted Lowry acid | donates proton (H) |
| Bronsted Lowry base | accepts proton (H) |
| smaller pKa | stronger acid |
| larger pKa | weaker acid, stronger base |
| increase in electronegativity | increases acidity |
| increase atomic size | increases acidity |
| inductive effect | pull of e- density through sigma bonds caused by electronegativity differences of atoms |
| increase inductive effect | more electronegative atom, closer to site of neg chg |
| increase resonance stability | increase acidity |
| salt | organic cpd with opposite formal chges adjacent |
| increase melting point | increase bond strength and symmetry |
| increase boiling point | increase bond strength and surface area |
| conformation | 3d arrangement of atoms/mlcls in space |
