aromatic nomentclature+ rules

toluene

phenol

anisole

aniline

benzoic acid

benzaldehyde

acetophenone

styrene

huckels rule

Aromatic if the amount of electron pairs is even. Count each end of double bond

count negative charges

dont count positive charge

aromatic rules

1. must be a ring with continuously overlapping P orbitals

2. huckels= must be even

remember make resonance structures

2n+1

annulene

fully conjugated pi system

On a ring with a substituent, where does a reaction take place?

At the benzylic position

reduction of benzene rings

How to know if an element satisfies huckel/ has a p orbital

count if there is an even amount of valence

huckel numbers

count each bond as

4n+2→ 2,6,10,14——aromatic

4n→4,8,12——antiaromatic
