Phenyl group
Encyclopedia : P : PH : PHE : Phenyl group
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 manner. It is highly stable. This hydrophobic and aromatic hydrocarbon unit can be found in many organic compounds. It can be thought of as being derived from benzene (C6H6). One of the simplest phenyl containing compounds is phenol.
Presence of a phenyl group typically results in an 1H-NMR shift around 7.4ppm.
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.
