4-Isopropenylphenol is an organic compound with the formula CH 2 =(CH 3)CC 6 H 4 OH. The molecule consists of a 2-propenyl group (CH 2 = C -CH 3 ) affixed to the 4 position of phenol . The compound is an intermediate in the production of bisphenol A (BPA), 2.7 Mkg/y of which are produced annually (2007).
Heptanone may refer to the following ketones with seven carbon atoms the formula C 7 H 14 O: . 2-Heptanone (Methyl amyl ketone) . 5-Methyl-2-hexanone (Methyl isoamyl ketone); 4-Methyl-2-hexanone (Methyl 2-methylbutyl ketone)
For example, the three isomers of xylene CH 3 C 6 H 4 CH 3, commonly the ortho-, meta-, and para-forms, are 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4-dimethylbenzene. The cyclic structures can also be treated as functional groups themselves, in which case they take the prefix "cycloalkyl-" (e.g. "cyclohexyl-") or for benzene, "phenyl-".
4-Isopropylphenol is an organic compound with the formula (CH 3) 2 CHC 6 H 4 OH. The molecule consists of an isopropyl group affixed to the para ( p -) position of phenol . The compound, a white solid, is produced by the alkylation of phenol with propylene and is relevant to the production of the commodity chemical bisphenol A (BPA).
1,1,1,3,3,3-Hexachloropropane is a compound of chlorine, hydrogen, and carbon, with chemical formula C 3 Cl 6 H 2, specifically Cl 3 C−CH 2 −CCl 3.Its molecule can be described as that of propane with chlorine atoms substituted for the six hydrogen atoms on the extremal carbons. [4]
The main structure of chemical names according to IUPAC nomenclature. The International Union of Pure and Applied Chemistry (IUPAC) has published four sets of rules to standardize chemical nomenclature. There are two main areas: IUPAC nomenclature of inorganic chemistry (Red Book) IUPAC nomenclature of organic chemistry (Blue Book)
Clar's rule states that for a benzenoid polycyclic aromatic hydrocarbon (i.e. one with only hexagonal rings), the resonance structure with the largest number of disjoint aromatic π-sextets is the most important to characterize its chemical and physical properties. Such a resonance structure is called a Clar structure. In other words, a ...
