Let the oxidation state of

Cr

in all cases is '

x

' (i) Oxidation state of

Cr

[Cr (H_{2} O)_{6}] Cl_{3}

x + (0 \times 6) + (- 1 \times 3) = 0

x + 0 - 3 = 0

x = + 3

(ii) Oxidation state of

Cr

[Cr (C_{6} H_{6})_{2}]

x + (2 \times 0) = 0 or x = 0

(iii) Oxidation state of

Cr

K_{2} [Cr (CN)_{2} (O)_{2} (O_{2}) (NH_{3})]

1 \times 2 + x + (- 1 \times 2) + (- 2 \times 2)

+(-2)+0=0

or 2 + x - 2 - 4 - 2 = 0

or x - 6 = 0

hence x = + 6

Thus,

+ 3, 0

and

+ 6

is the answer.
