Nomenclature and structure of other functional groups Flashcards
Were used to describe fragrant substance
Aromatic compounds
From coal distillate
Benzene
From cherries, peaches, and almonds
Benzaldehyde
From tolu balsam
Toluene
Aromatic compounds are now used to describe cyclic organic compounds with:

No, is separated from alcohol, but considered as derivative of benzene
2 substituent benzene
Name of substituent
Name of Benzene derivative
2 substituent benzene, name of substituent
position (similar to cycloalkanes)
True or false: Only on benzene can ortho, meta, and para be used
true
ortho (o)
1,2
meta (m)
1,3
Para (p)
