Answer 2

Answer:

IUPAC name of [CrF6]3- is Hexafluorochromate(III).

Explanation:

The rules of naming coordination compounds with anionic ligands are:

• The magnetic properties, isomers, etc. are different in coordination compounds which makes their nomenclature different from other compounds.
• Ligands (here fluoride) are named first. In the case of more than one ligands, they are alphabetically written.
• Then, the metal ion (Chromium) is named. In anionic coordination complex, -ate is added to the metal ion as suffix.
• Here, the ligand is ending with -ide, which is replaced by the suffix -o.
• Then, the oxidation state in roman numeral is written.

Hence, the IUPAC name of the given compound is Hexafluorochromate(III).
