Answers, With Complete Solution, 2024.

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
1C
eth
2C
prop
3C
but
4C
pent
5C
hex
6C
hept

IUPAC Naming Rules

, 1.substituent-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




isobutyl




tert-butyl




phenyl/benzene ring
