phenyl
Quick Summary
The term "phenyl" refers to a chemical group derived from benzene, represented as C6H5−. It is a monovalent aryl radical, meaning it's a part of a molecule that can form chemical bonds. The prefix "phen-" is often used in chemical names to indicate a relation to benzene or the presence of a phenyl group.12
Phenyl is a fundamental component in various organic compounds. For example, it is found in phenylalanine, an essential amino acid crucial for mammals and fowls, which cannot produce it themselves and must obtain it through their diet. Phenyl isocyanate is another compound, a liquid used in chemical identification processes. Phenylethyl refers to radicals derived from ethylbenzene.345

polystyreneThe presence of the pendant phenyl (C6H5) groups is key to the properties of polystyrene. Solid polystyrene is transparent, owing to these large, ring-shaped molecular groups, which prevent the polymer chains from packing into close, crystalline arrangements. In addition, the phenyl rings restrict rotation of the chains around the carbon-carbon…
