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 ...
IUPAC nomenclature is used for the naming of chemical compounds, based on their chemical composition and their structure. [1] For example, one can deduce that 1-chloropropane has a Chlorine atom on the first carbon in the 3-carbon propane chain.
Although most compounds are referred to by their IUPAC systematic names (following IUPAC nomenclature), ... (III) nitrate–BiN 3 O 9 [130] Bismuth(III) oxide – Bi ...
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.
This naming method generally follows established IUPAC organic nomenclature. Hydrides of the main group elements (groups 13–17) are given -ane base names, e.g. borane, BH 3. Acceptable alternative names for some of the parent hydrides are water rather than oxidane and ammonia rather than azane.
3 COOH, which is commonly called acetic acid and is also its recommended IUPAC name, but its formal, systematic IUPAC name is ethanoic acid. The IUPAC's rules for naming organic and inorganic compounds are contained in two publications, known as the Blue Book [ 1 ] [ 2 ] and the Red Book , [ 3 ] respectively.
The groups are on carbon atoms 3 and 9. As there are two, we write 3,9-dione. The numbering of the molecule is based on the ketone groups. When numbering from left to right, the ketone groups are numbered 3 and 9. When numbering from right to left, the ketone groups are numbered 15 and 21. 3 is less than 15, therefore the ketones are numbered 3 ...
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 ...
