Aryl
Groups or Aryl Radicals
Definition of Aryl Radicals
Aryl
groups are the basic structural unit of all aromatic organic compounds.
The
residual hydrocarbon group or radical left after the removal of a hydrogen atom
from arenes or aromatic compounds is called an aryl group or radical.
Stated differently, the radicals obtained from arenes by the removal of one
hydrogen atom are called aryl group or radical. They are generally represented
by ‘Ar–’.
The
most fundamental aryl group is called phenyl group obtained by removing
one hydrogen atom from benzene or phene. Its formula is C6H5–
and it is denoted by Ph.
