MCQ
What is the oxidation state of central atom in Ca[PtCl4​]?
  • A
    1
  • B
    2
  • C
    3
  • D
    4
✓

Answer

  1. 2

Explanation:

Ca[PtCl4​] ⇔ Ca+2[PtCl4​]2−

Take [PtCl4​]2−. Central atom = Pt.

Let x be the oxidation no. of Pt,

Cl oxidation no. is −1.

x + 4(−1) = −2

x − 4 = −2

x = 2
