Level 4-Naming Benzenes

 

 

more about benzene

Benzenes-

The rule for naming is they all end with "benzene".

The general formula is CnH2n-6, n is the number of carbons is used to determine the number of hydrogen atoms. Example n=8, so H=(2(8)-6)=10

C8H10

 

Naming Compounds- Again, ignore all the hydrogen's. We only worry about carbon atoms.

Rule #1-Name the benzene ring.  End it with "benzene".

Rule #2-When necessary use the lowest number to give the locations of side chains that come off the benzene.

C6H6 benzene
C7H8 methyl benzene

"toluene"

C8H10 ethyl benzene
C9H12 propyl benzene
2,4,6-trinitrotoluene
