Phenyl group
From Wikipedia, the free encyclopedia
In chemistry, the phenyl group or phenyl ring (often abbreviated as -Ph) is the functional group with the formula
where the six carbon atoms are arranged in a cyclic ring structure. It is highly stable, and is also a member of the aromatic family of compounds. This hydrophobic and aromatic hydrocarbon unit can be found in many organic compounds. It can be thought of as being derived from benzene (C6H6). In fact in chemical literature benzene itself is sometimes denoted as Ph. One of the simplest phenyl containing compounds is phenol, C6H5OH.
Presence of a phenyl group typically results in an 1H-NMR shift around 7.7ppm.
The phenylene group is formally a benzene di-radical. For example, poly(p-phenylene) is a polymer built up from phenylene repeating units.
This functional group differs from the benzyl functional group in that benzyls have an extra CH2.ar:فينيل (Phenyl) de:Phenylgruppe es:Fenil pl:Grupa fenylowa tr:Fenil zh:苯基
