A naphthalene molecule can be viewed as the fusion of a pair of benzene rings. (In organic chemistry, rings are fused if they share two or more atoms.) As such, naphthalene is classified as a benzenoid polycyclic aromatic hydrocarbon (PAH). [19] The eight carbon atoms that are not shared by the two rings carry one hydrogen atom each.
Bottom: atomic force microscopy image. A polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings. The simplest representative is naphthalene, having two aromatic rings, and the three-ring compounds anthracene and phenanthrene. PAHs are uncharged, non-polar and planar.
Aliphatic compound. In organic chemistry, hydrocarbons (compounds composed solely of carbon and hydrogen) are divided into two classes: aromatic compounds and aliphatic compounds (/ ˌælɪˈfætɪk /; G. aleiphar, fat, oil). Aliphatic compounds can be saturated (in which all the C-C bonds are single requiring the structure to be completed, or ...
Naphthenic acid can refer to derivatives and isomers of naphthalene carboxylic acids. In the petrochemical industry, NA's refer to alkyl carboxylic acids found in petroleum. [3] The term naphthenic acid has roots in the somewhat archaic term "naphthene" (cycloaliphatic but non-aromatic) used to classify hydrocarbons.
1-Naphthaleneacetic acid (NAA) is an organic compound with the formula C 10 H 7 CH 2 CO 2 H. This colorless solid is soluble in organic solvents. This colorless solid is soluble in organic solvents. It features a carboxylmethyl group (CH 2 CO 2 H) linked to the "1-position" of naphthalene .
Cycloalkane. Ball-and-stick model of cyclobutane. In organic chemistry, the cycloalkanes (also called naphthenes, but distinct from naphthalene) are the monocyclic saturated hydrocarbons. [1] In other words, a cycloalkane consists only of hydrogen and carbon atoms arranged in a structure containing a single ring (possibly with side chains), and ...
Phthalic anhydride is the organic compound with the formula C 6 H 4 (CO) 2 O. It is the anhydride of phthalic acid. Phthalic anhydride is a principal commercial form of phthalic acid. It was the first anhydride of a dicarboxylic acid to be used commercially. This white solid is an important industrial chemical, especially for the large-scale ...
Properties. Quinones are oxidized derivatives of aromatic compounds and are often readily made from reactive aromatic compounds with electron-donating substituents such as phenols and catechols, which increase the nucleophilicity of the ring and contributes to the large redox potential needed to break aromaticity.
