SOPBAR - used to find degrees of unsaturation ((2C+2)-H-X+N)/2 Resonance Rules - -no breaking single bonds -do not exceed octet -keep net charge the same -try to have full octets (most stable) Resonance Patterns - 1. Lone pair e- next door to pi bond 2. Pi bond next to positive charge 3. Double bond btwn atoms of differing electronegativity (ex: carbonyl) Curved Arrows - show movement of pair of electrons *start at lone pair or double bond* Hybridization - sp3= tetrahedral, four domains sp2=trig planar, three domains (double bond counts only as 1) meth - 1 C eth - 2 C prop - 3 C but - 4 C pent - 5 C hex - 6 C hept - 7 C oct - 8 C non - 9 C dec - 10 C IUPAC Naming Rules - ituent-parent-suffix *suffix is highest priority substituent* 2. Numbers correspond with location on parent chain (longest continuous carbon chain) 3. List substituents alphabetically (tert, sec, di, tri do not count...) 4. Highest priority substituent gets lowest number C 5. Halogens are substituents (will not be suffix) propyl - isopropyl - butyl - 4 C, attached on primary carbon sec-butyl -
