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)
Co + H 2 SO 4 + 7 H 2 O → CoSO 4 (H 2 O) 7 + H 2 CoO + H 2 SO 4 + 6 H 2 O → CoSO 4 (H 2 O) 7. The heptahydrate is only stable at humidity >70% at room temperature, otherwise it converts to the hexahydrate. [2] The hexahydrate converts to the monohydrate and the anhydrous forms at 100 and 250 °C, respectively. [1] CoSO 4 (H 2 O) 7 → CoSO ...
The names "caffeine" and "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound. The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" simply names it.
Although most compounds are referred to by their IUPAC systematic names (following IUPAC nomenclature), ... Iron(III) nitrate – Fe(NO 3) 3 (H 2 O) 9; Iron(III ...
For esters such as ethyl acetate (CH 3 COOCH 2 CH 3), ethyl formate (HCOOCH 2 CH 3) or dimethyl phthalate that are based on common acids, IUPAC recommends use of these established names, called retained names. The "-oate" changes to "-ate." Some simple examples, named both ways, are shown in the figure above.
58-55-9 C 7 H 8 N 4 O 2: theobromine: C 7 H 9 BO 2: 4-methylphenylboronic acid: 5720-05-8 C 7 H 9 BO 3: 4-boronoanisole: 5720-07-0 C 7 H 10 N 2: 4-dimethylaminopyridine: 1122-58-3 C 7 H 11 NO 5: N-Acetylglutamic acid: C 7 H 12 O 4: diethyl malonate: C 7 H 12 N 2 O 4: aceglutamide: C 7 H 14 O 3: n-Butyl lactate: 138-22-7 C 7 H 14 O 6: bornesitol ...
cdco 3 + h 2 so 4 → cdso 4 + h 2 o + co 2 Although written with simple anhydrous formulas, these conversions generally are conducted in the presence of water. Consequently the product sulfates are hydrated , corresponding to zinc sulfate ZnSO 4 ·7H 2 O , copper(II) sulfate CuSO 4 ·5H 2 O , and cadmium sulfate CdSO 4 ·H 2 O .
A detailed product analysis of a large-scale synthesis revealed that one minor by-product was [Co(en) 2 Cl(H 2 NCH 2 CH 2 NH 3)]Cl 3, which contains a rare monodentate ethylenediamine ligand (protonated). [2] The cation [Co(en) 3] 3+ is octahedral with Co-N distances in the range 1.947–1.981 Å. The N-Co-N angles are 85° within the chelate ...
