|Aromatic Compounds and Their Derivatives
|Alkyl compounds where made from straight chains and cyclics of
straight chains. Aromatic compounds are made from benzene and its derivatives.
It is a six-membered ring with three double bonds. The double bonds alternate
and move around the ring which make them hard to attack and break. For this
reason benzene is a very stable molecule. A short form version of the ring
consists of a hexagon indicating the six-membered C ring and a circle in the
middle indicating the alternating three double bonds.
|The alternating double bonds fluctuate or resonate around the ring.
The resonating bonds are difficult to attack and this makes the benzene ring
structure very stable. Substitutions can be made to each of the hydrogens
on the ring but breaking the ring itself is difficult. The short form
version of the above structure is below.
|Special Compound Derivatives of Benzene|
|There are two ways to name benzene ring compounds. The C's on the ring can be numbered in order starting from the most important add-on radical or we can use the ortho, meta, para system. See the diagram below for the placement of these names.|
|The following molecules are all derivatives of benzene. Since they are very common these are all used as parent names from which other more complex names can be derived.|
