In the complex, [Cr(NH_3)_4 Cl_2]^ + , the oxidation number of Cr is

In the complex, [Cr(NH3)4Cl2]+\left[\mathrm{Cr}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}, the oxidation number of Cr is

Options

  1. A+4+4
  2. B+3+3
  3. C+2+2
  4. D+6+6

Correct answer

B. +3+3

Step-by-step solution

Let the oxidation number of Cr is x in the complex [Cr(NH3)4Cl2]+\left[\mathrm{Cr}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}∴X+4×(0)+2×(−1)=+1x−2=+1x=+3\begin{aligned} \therefore \quad \mathrm{X}+4 \times(0)+2 \times(-1) & =+1 \\ x-2 & =+1 \\ x & =+3\end{aligned}$$ Thus, the oxidation number of Cr is +3 .
