Explanation:

Answer 2

Answer:

The IUPAC name of (NH₄)₃[Fe(SCN)₆] is Ammonium hexathiocyanatoferrate(III).

Explanation:

• When we write the IUPAC name of a coordination compound, the name of cation is used to write first, followed by the name of anion.

• The name of all the ligands are written in alphabetical order. The prefix with ligands indicates the number of ligands attached with the central metal ion.

• The oxidation state of metal ion will be written in Romans numerous.

For the given coordination compound (NH₄)₃[Fe(SCN)₆] :-

The six thiocyanato-S ligands attached to iron metal through S-linkage. The NH₄⁺ is the cationic part and [Fe(SCN)₆]³⁻ is anionic part. The oxidation of Fe is:-

      $x+6(-1)=-3$

      $x=6-3$

      $x=+3$

Therefore the IUPAC name of (NH₄)₃[Fe(SCN)₆] is Ammonium hexathiocyanatoferrate(III).
