The structure of the phenyl group

In chemistry, the phenyl group or phenyl ring (often abbreviated as -Ph) is the functional group with the formula

-C₆H₅

where the six carbon atoms are arranged in a cyclic ring structure. Chemistry (from Egyptian kēme (chem meaning "earth") is the Science concerned with the composition structure and properties In Organic chemistry, functional groups are specific groups of Atoms within Molecules that are responsible for the characteristic Chemical reactions Carbon (kɑɹbən is a Chemical element with the symbol C and its Atomic number is 6 Hydrogen (ˈhaɪdrədʒən is the Chemical element with Atomic number 1 It is in the Aryl group. In the context of organic molecules aryl refers to any Functional group or Substituent derived from a Simple aromatic ring, may it be Phenyl 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. In Chemistry, hydrophobicity (from the combining form of water in Attic Greek hydro- and for fear phobos) refers to the physical property of In Organic chemistry, a hydrocarbon is an Organic compound consisting entirely of Hydrogen and Carbon. An organic compound is any member of a large class of Chemical compounds whose Molecules contain Carbon. It can be thought of as being derived from benzene (C₆H₆). Benzene, or benzol, is an organic Chemical compound and a known Carcinogen with the molecular formula C 6 H 6 Carbon (kɑɹbən is a Chemical element with the symbol C and its Atomic number is 6 Hydrogen (ˈhaɪdrədʒən is the Chemical element with Atomic number 1 In fact, in chemical literature benzene itself is sometimes denoted as Ph. One of the simplest phenyl containing compounds is phenol, C₆H₅OH. Phenol, is a toxic colourless Crystalline Solid with a sweet tarry odor commonly referred to as a "hospital smell" The resonance stability of phenol makes it a stronger acid than that of another alcohol (pKa = 10 vs. Resonance in Chemistry is a theory used to represent and model certain types of non-classical Molecular structures Resonance is a key component In Computer science, ACID ( Atomicity Consistency Isolation Durability) is a set of properties that guarantee that Database transactions are In Chemistry, an alcohol is any Organic compound in which a Hydroxyl group ( - O[[hydrogen H]]) is bound to a Carbon 16-18).

Presence of a phenyl group typically results in an ¹H-NMR shift around 7. 7ppm.

The phenyl group differs from the benzyl functional group in that benzyls have an extra CH₂. In Organic chemistry, benzyl is the term used to describe the Substituent or molecular fragment possessing the structure C6H5CH2- Methylene is the chemical species R2C named after Methane, in which two of the carbon atom's valence electrons form no bonds These phenyl groups can also be found in polymers such as polystyrene. A polymer is a large Molecule ( Macromolecule) composed of repeating Structural units typically connected by Covalent Chemical bonds Polystyrene ˌpɒliˈstaɪriːn ( IUPAC Polyphenylethene is an aromatic Polymer made from the aromatic Monomer Styrene
