Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula C6H5OH. [ 5 ] It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C6H5) bonded to a hydroxy group (−OH).
In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (−O H) bonded directly to an aromatic hydrocarbon group. [1] The simplest is phenol, C 6 H 5 OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the ...
In chemistry, an alcohol (from the Arabic word al-kuḥl, الكحل) is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. [ 2 ][ 3 ] Alcohols range from the simple, like methanol and ethanol, to complex, like sugars and cholesterol. The presence of an OH group strongly ...
Diatomic molecule. Diatomic molecules (from Greek di- 'two') are molecules composed of only two atoms, of the same or different chemical elements. If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H2) or oxygen (O2), then it is said to be homonuclear. Otherwise, if a diatomic molecule consists of two different ...
Structural isomer. In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature [ 1 ]) of a compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct bonds between them. [ 2 ][ 3 ] The term metamer was formerly used for the same concept. [ 4 ]
Chemical bond. Covalent bonding of two hydrogen atoms to form a hydrogen molecule, H. 2. In (a) the two nuclei are surrounded by a cloud of two electrons in the bonding orbital that holds the molecule together. (b) shows hydrogen's antibonding orbital, which is higher in energy and is normally not occupied by any electrons.
Polyphenols (/ ˌpɒliˈfiːnoʊl, - nɒl /) are a large family of naturally occurring phenols. [ 1 ] They are abundant in plants and structurally diverse. [ 1 ][ 2 ][ 3 ] Polyphenols include phenolic acids, flavonoids, tannic acid, and ellagitannin, some of which have been used historically as dyes and for tanning garments.
Oxidative coupling of phenols is a chemical reaction wherein two phenolic compounds are coupled via an oxidative process. Oxidative phenol couplings are often catalyzed by transition metal complexes including V, Cr, Mn, Cu, Fe, among others. Such reactions often form C–C, or C–O bonds between the coupling partners and can be employed as ...
