Question

The IUPAC name of the complex [Ag(H₂O)₂] [Ag(CN)₂] is ______.

Options

• diaquasilver (II) dicyanidoargeltate (II)

• dicyanidosilver (I) diaquaargentate (I)

• diaquasilver (I) dicyanidoargentate (I)

• dicyanidosilver (II) diaquaargentate (II)

Answer 1

The IUPAC name of the complex [Ag(H₂O)₂] [Ag(CN)₂] is diaquasilver (I) dicyanidoargentate (I).

Explanation:

[Ag(H₂O)₂]: Silver (I) coordinated with two water molecules, called diaqua.

[Ag(CN)₂]: Silver (I) coordinated with two cyanide ions, called dicyanido.

Silver (I) and Argentate (I) both indicate the oxidation state of silver is +1 in both parts of the complex.

Thus, the full name is Diaquasilver(I) dicyanidoargentate(I).
