Question

The total number of electrons donated by ligands to platinum ion in $\left[Pt(en{)}_{2}C{l}_2\right]$ is

• A. 8
• B. 10
• C. 12
• D. 14

Answer 1

Answer: (C)

In $\left[Pt(en{)}_{2}C{l}_2\right]$, there are $2$ monodentate and $2$ bidentate ligands.
Hence, electrons donated by ligands $=2\times 2+2\times 4$
$=4+8$
$=12$
