Effective atomic number of $Pt$ in $[PtCl_6]^{2-} = 84$

Vedclass · Answer

(A) The $EAN$ (Effective Atomic Number) is calculated as: $EAN = Z - 	ext{oxidation state} + 2 	imes 	ext{coordination number}$.
For $[PtCl_6]^{2-}$,the atomic number of $Pt$ $(Z)$ is $78$.
The oxidation state of $Pt$ is $x + 6(-1) = -2$,so $x = +4$.
The coordination number is $6$.
$EAN = 78 - 4 + 2(6) = 74 + 12 = 86$.
Since the given value in option $A$ is $84$,it is incorrectly matched.

Which of the following pairs is not correctly matched?
