naming rules Flashcards
Parent examples
Phenol, aniline, etc
Naming formula
Parent, subs, number subs
Cyclohexene plus Br2
Anti addn
Benzene plus Br2
No rxn bc benzene is aromatic
How to do a frost circle
- Draw a circle
- Draw polygon inside it
- Line for each corner
- Dotted line in middle
- Fill in e-
If paired and below center line- aromatic. If above- antiaromatic (very unstable)
If a compound doesn’t have a flat ring with overlapping p orbitals, it is
nonaromatic
if a compound has a flat ring with overlapping p orbitals but doesn’t have 4N+2 pi electrons, it is
Antiaromatic
A lone pair in a P orbital counts as
pi electrons
Benzylic position
Directly connected to benzene ring
NaCr2O7, H2SO4
Strong oxidizing agent (Alkane chain to CO2H)
H2O, Heat
SN1 Substitution reaction with OH
NaOH
SN2 substitution with OH
Concentrated H2SO4
E1 elimination
NaOH
E2 elimination
3H2, Ni, high pressure and temp
Turns benzene to cyclohexane
H2, Pt, low pressure and temp
Removes DB from vincyclic position
Birch reduction
Na, MeOH, NH3- removes DB
Birch mechanism (page 12)
If EWG present with birch
Pi bonds paralell to group
If EDG present with birch
Pi bonds intersect with group
