AROMATIC RINGS Flashcards
Aromatic describes what
derivatives of benzene.
when is the term benzene used and when is the term phenyl used
benzene = mono-substituted rings where parent chain is less than 6c or less
phenyl group = where parent chain is more than 6c
if not the entire 6C ring group drawn out, what is phenyl also represented in words that is sometimes drawn on diagrams
Ph
what is a benzene ring with a methyl group on carbon 1 called
toluene
what is a benzene ring with a OH group on carbon 1 called
phenol
what is a benzene ring with a O-CH3 group on carbon 1 called
anisole
what is a benzene ring with a O-NH2 group on carbon 1 called
aniline
when two substituents are attached to a benzene ring, what are the three possible isomer terms
-ortho
-meta
-para
what is it called if the two substituents are right next to each other on a benzene ring
ortho
what is it called if the two substituents are C1 and C3 on a benzene ring
meta
what is it called if the two substituents are C1 and C4 on a benzene ring
para
what are xylenes
formula₂C₆H₄
derived from the substitution of two hydrogen atoms with methyl groups in a benzene ring
can ortho, meta, para be used in any benzene substituent amount
only in 2
polysubstituted compounds must be named in original iupac naming
what is the naming procedure involving benzene
- Identify and name the parent
- Identify and name the substituents
- Assign a location (number) to each substituent
- Arrange the substituents in alphabetical order to determine the name
