Aromatic Hydrocarbons PPT

is the generic term for an aromatic hydrocarbon

is derived by removal of a hydrogen

Aromatic compounds undergo what kind of reaction

draw the halogenation reaction and its reactants

draw the nitration reaction and its reactans

has a full or positive charge

draw the sulfonation reaction and its needed reactants

draw the friedel crafts alkylation

draw the friedel crafts acylation

In step 1 of the mechanism, the electrophile reacts with two p electrons from the aromatic ring to form a what

In step 2, a wha is removed and the aromatic system is regenerated

generation of arenium ion is what kind of rxn

The first step requires the loss of aromaticity of the very stable benzene ring, which is highly unfavorable thus the first step is rate ____

second step wherein the ring gains it aromatic substitution is highly

which has a larger DG‡, first or second step

The ring regains its aromatic stabilization, a highly favorable/unfavorable process

Halogenation of benzene requires the presence of a what

A special apparatus is used to perform this reaction

occurs so rapidly it is hard to stop at monofluorination of the ring

is so unreactive that an alternative method must be used

draw the iodination reaction

in nitration, the nitric acid can dissociate to form a what

is the actual electrophile in nitration; it reacts with benzene to form a resonance-stabilized arenium ion

Sulfonation occurs most rapidly using what
