Chapter 4: Aromatic Compounds
Bitter almonds are the source of the aromatic compound benzaldehyde
Slide2Sources of Benzene
Slide3Some Facts About Benzene
Reacts mainly by substitution
Slide4Friedrich August Kekule’
Slide5The Orbital Model for Benzene
Symbols for Benzene
Slide6Nomenclature of Aromatic Compounds
Monosubstituted benzenes with common names
Slide7Monosubstituted benzenes that do not have common names
Slide8When two substituents are present, we use prefixes
ortho-
,
meta-
, and
para-,
usually abbreviated as o-, m-, and p-, respectively.
Slide9Slide10For more than two substituents, their positions are designated by numbering the ring.
Slide11Aromatic hydrocarbons, as a class called Arenes (Ar) the aryl groups are therefore aromatic substituents.
Slide12The symbol Ph is sometimes used as an abbreviation for phenyl group
