Carboxylic acids attached to a benzene ring are structural analogs of benzoic acid (Ph−COOH) and are named as one of its derivatives. Citric acid. If there are multiple carboxyl groups on the same parent chain, multiplying prefixes are used: Malonic acid, CH 2 (COOH) 2, is systematically named propanedioic acid.
This category includes chemical compounds that are derivatives or structural analogs of benzene in which the benzene has multiple substituents or bonds. For benzene derivatives that include a phenyl group , C 6 H 5 – (benzene with only one substituent or bond), see the child category, Category:Phenyl compounds .
Chemical nomenclature however (with IUPAC nomenclature as the best example) is necessarily more restrictive: Its purpose is to standardize communication and practice so that, when a chemical term is used it has a fixed meaning relating to chemical structure, thereby giving insights into chemical properties and derived molecular functions. These ...
Benzyl group and derivatives: Benzyl group, benzyl radical, benzyl amine, benzyl bromide, benzyl chloroformate, and benzyl methyl ether. R = heteroatom, alkyl, aryl, allyl etc. or other substituents. In organic chemistry, benzyl is the substituent or molecular fragment possessing the structure R−CH 2 −C 6 H 5.
For compounds consisting of one benzene ring with only chlorine and hydrogen as substituents, see Category:Chlorobenzenes. Subcategories This category has the following 3 subcategories, out of 3 total.
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
In ortho-substitution, two substituents occupy positions next to each other, which may be numbered 1 and 2.In the diagram, these positions are marked R and ortho.; In meta-substitution the substituents occupy positions 1 and 3 (corresponding to R and meta in the diagram).
The C 3-benzenes are a class of organic aromatic compounds which contain a benzene ring and three other carbon atoms. For the hydrocarbons with no further unsaturation, there are four isomers. The chemical formula for all the saturated isomers is C 9 H 12 .
