Question

Give the IUPAC name of ${K_3}[Cr{({C_2}{O_4})_3}]$ .

Answer 1

Hint : To answer this question, we first need to understand what IUPAC is. The International Union of Pure and Applied Chemistry (IUPAC) is a global federation of National Adhering Organizations that represents chemists from all over the world. The International Science Council has accepted it as a member.

Complete Step By Step Answer:
Compound naming - A chemical nomenclature is a set of principles for naming chemical substances in a systematic way. The International Union of Pure and Applied Chemistry designed and developed the nomenclature that is most often used around the world.
The Blue Book and the Red Book are two books that provide the IUPAC's standards for naming organic and inorganic substances, respectively. A third volume, dubbed the Green Book, explains how to utilize symbols for physical quantities, while a fourth, dubbed the Gold Book, contains explanations for many chemistry-related terminology. Biochemistry, analytical chemistry, and macromolecular chemistry have similar compendia.
Potassium tris oxalato chromate - In most volumes, potassium chromium (III) oxalate trihydrate (or potassium tris(oxalate) chromate trihydrate) is readily available. Submicron and nano powder forms of high purity may be considered. When applicable, American Elements follows ASTM testing standards and produces to various standard grades, including Mil Spec; ACS, Reagent and Technical Grade; Food, Agricultural, and Pharmaceutical Grade; Optical Grade, USP, and EP/BP (European Pharmacopoeia/British Pharmacopoeia).
So, we conclude that, ${K_3}[Cr{({C_2}{O_4})_3}]$ Potassium tris oxalato chromate is the IUPAC designation for it (III). Because it is bound to three bi-dentate ligands, the coordination number will be 6. The number of ligands linked to the central metal ion multiplied by the ligand's denticity gives the compound's coordination number.

Note :
In summary, the name of the compound is written in alphabetical order with the substituents first, then the base name (derived from the number of carbons in the parent chain). Between numbers, commas are used, while between letters and numbers, dashes are used. The name has no spaces in it.
