Name the following compound: [Cr(H2O)4Cl2]Cl dichlorotetraaquachromium(III) chloride tetraaquadichlorochromium(III) chloride tetraaquadichlorochromium(II) chloride dichlorotetraaquachromium(IV) chloride.

Respuesta :

Answer:

tetraaquadichlorochromium(III) chloride

Explanation:

Given,  

The complex : [Cr(H₂O)₄Cl₂]Cl

The oxidation number of Chromium is:

x +0 +2(-1) = +1

x = +3

The complex contains ligands  H₂O and chloride ion.

Cl⁻ is written as chloro and H₂O as aqua. H₂O is written first because aqua will come before chloro in the English alphabet.

4 molecules of H₂O are acting as ligands in the complex. So, written as: tetraaqua

2 molecules of Cl⁻ are acting as ligands in the complex. So, written as: dichloro

One chloride ion acts as a spectator anion.

The name of the complex is:

tetraaquadichlorochromium (III) chloride
