Question

[Cr ( Ox )3] [ Cr (NH3)6 ]

Answer 1

Explanation:

hexaamminechromium(III) trioxalatochromate(III)

Additional information :-

Here, [Cr(NH3)6] is cationic complex. So, here we apply cationic rule.

Then,

IUPAC Name of Cationic complex is hexaamminechromium()

• At last we calculate O.N. then we put O.N. in last

Now,

In Anionic complex [Cr(ox)3]. Here we apply anionic rule

Then,

IUPAC Name of anionic complex is

Trioxalatochromate()

Now,

Calculation of O.N. :-

Let the oxidation number of Cr in cationic complex is x.

And

Oxidatkn number of Cr in anionic complex is y.

Then,

→ x -2×3 + y + 0×6 = 0

→ x + y = 6

Now,

Here we divide 6 in two equal parts.

It means,

x = 3 and y = 3

Now, we put O.N. in both

Hence,

IUPAC Name is hexaamminechromium(III) trioxalatochromate(III)
