Question: The oxidation number of \(Pt\) in \(\lbrack Pt(C_{2}H_{4})Cl_{3}\rbrack^{-}\) is....

The oxidation number of PtPt in [Pt(C2H4)Cl3]−\lbrack Pt(C_{2}H_{4})Cl_{3}\rbrack^{-} is.

A
  • 1
B
  • 2
C
  • 3
D
  • 4
Answer
  • 2
Explanation

Solution

[Ptx(C20H4)Cl3−1]−\lbrack\underset{x}{Pt}\underset{0}{(C_{2}}H_{4})\underset{- 1}{Cl_{3}}\rbrack^{-}

x+0+3x(−1)=−1x + 0 + 3x( - 1) = - 1, x−3=−1,x - 3 = - 1, x=+2.x = + 2.
