AROMATIC HYDROCARBONS Flashcards
It was first isolated in 1825 from the oily residues after heating whale oil
Benzene or C6H6
Benzene was isolated by in
1825 by Michael Faraday
In 1834 benzene’s was prepared from
Benzoic acid
Benzobic acid was obtained from the chemical degradation of
Gum benzoin
It is the parent hydrocarbon of the especially stable compounds known as aromatic compounds
Benzene
It is the term that came to mean any compound structurally derived from benzene
Aromatic
This compounds are hydrocarbons that contain a benzene ring as a structural unit
Aromatic hydrocarbons
In addition to benzene other examples include
Toluene and napthalene
The most common reactions of aromatic compounds involve
Substitution
The most common reactions of aromatic compounds involved substitution of other atoms or groups for a ring hydrogen on the aromatic unit or more precisely called
Electrophilic aromatic substitution reaction
The halogenation of aromatic hydrocarbons include
Bromination and chlorination of benzene
Bromination and chlorination of benzene requires a Lewis acid such as
Ferric bromide / ferric chloride
Electrophilic iodine is obtained by treating iodide with an oxidizing agent such as
Nitric acid
Nitration of benzene with nitric acid requires what acid as a catalyst
Sulfuric acid
A sulfuric acid is a strong acid because of what
Three electron withdrawing oxygen atoms and the stability of its conjugate base
