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 .
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.
For benzene derivatives (derivatives or structural analogs of benzene) in which benzene has multiple substituents or bonds, see the parent category, Category:Benzene derivatives. Subcategories This category has the following 12 subcategories, out of 12 total.
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.
Alkylbenzenes are derivatives of benzene, in which one or more hydrogen atoms are replaced by alkyl groups. The simplest member, toluene (or methylbenzene), has the hydrogen atom of the benzene ring replaced by a methyl group. The chemical formula of alkylbenzenes is C n H 2n-6. [2] Safety hazards of toluene.
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 ...
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).
Heteroarenes are aromatic compounds, where at least one methine or vinylene (-C= or -CH=CH-) group is replaced by a heteroatom: oxygen, nitrogen, or sulfur. [3] Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one ...
