Priority of naming disubstituted groups
1. Ester
2. Acid (-COOH, -SO2H)
3. Aldehyde and Ketone (-CHO, -C- w. double bond to O)
4. Alcohol and Thiol (-OH, -SH)
5. Amino (-NH2)
6. Everything else (ether, halogen, -R, -OR (alkoxy) -NO2)
30
Naming Tri/Poly Substituted Benzene Derivative
1. Find derivative with unique name and make that 1
2. The second group will be whatever is closest, regardless of group attachment.
31
Criteria for Aromaticity
1. Molecule is **cyclic**
2. Molecule is **planar** (sp2 hybridized 120)
3. Each atom in the ring is a **conjugated p-orbital**
4. In this cyclic conjugated system there are **(4n+2) pi electrons**
Huckel #’s = **2,6,10,14,18,**etc.
n= any integer
