The earliest predictions about the structure of benzene could not completely explain some of its properties. Later it was found that benzene has a cyclic structure which is commonly represented as follows:
These two structures are resonance structures of benzene. Benzene is also commonly represented as shown below:
A series of reactions were conducted using benzene and other aromatic compounds.
In Reaction 1, benzene was reacted with n-propyl chloride in the presence of AlCl3.
Nitrobenzene was reacted with nitric acid and sulfuric acid. The reaction occurred as follows:
The reaction shown here is:
