These fragments were then used as building blocks in the structure generator. This structure generator was part of a CASE system, ESESOC. [23] Breadth-first search generation. Molecular structure generation is explained step by step. Starting from a set of atoms, bonds are added between atom pairs until reaching saturated structures.

Because the S 2− anion has a subscript of 2 in the formula (giving a 4− charge), the compound must be balanced with a 4+ charge on the Pb cation (lead can form cations with a 4+ or a 2+ charge). Thus, the compound is made of one Pb 4+ cation to every two S 2− anions, the compound is balanced, and its name is written as lead(IV) sulfide .
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-".
Alternatively, more explicit structure-based nomenclature can be used when the polymer structure is proven. Where there is no confusion, some traditional names are also acceptable. Whatever method is used, all polymer names have the prefix poly, followed by enclosing marks around the rest of the name. The marks are used in the order: {[( )]}.
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).
