Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In the complex [PtCl\(_6\)]\(^{2-}\), platinum (Pt) is coordinated to 6 chloride ions, so the coordination number of Pt is 6. In the complex [Fe(C\(_2\)O\(_4\))\(_3\)]\(^{3-}\), iron (Fe) is coordinated to 6 oxalate ions, so the coordination number of Fe is also 6.
Thus, the correct answer is (B).
