Question

If $H_x\left[Pt{y}_6\right]$, y is a monodentate negatively charged ligand then find out the value of x.

• A. $5$
• B. $3$
• C. $6$
• D. None of these

Answer 1

The correct option is D None of these

$H_x\left[Pt{y}_6\right]$ complex

If coordination number of $Pt=6$, then oxidation state of $Pt=+4$

By charge balance we get:

$\therefore x\times 1+4+6\times (-1)=0$

$\Rightarrow x=2$.
