What is the EAN of Zn in \(\left[\mathrm{Zn}\left(\mathrm{NH}_3\right)_4\right]^{2+}\) ?
- A 32
- B 28
- C 30
- D 36
Answer & Solution
Correct Answer
(D) 36
Step-by-step Solution
Detailed explanation
\(\mathrm{Z}=30, \mathrm{X}=2, \mathrm{Y}=8\)
EAN of \(\mathrm{Zn}^{2+}=\mathrm{Z}-\mathrm{X}+\mathrm{Y}=30-2+8=36\)
\((\mathrm{Z}=\) atomic number of metal, \(\mathrm{X}=\) charge on metal, \(Y=\) electrons donated by ligand.)
EAN of \(\mathrm{Zn}^{2+}=\mathrm{Z}-\mathrm{X}+\mathrm{Y}=30-2+8=36\)
\((\mathrm{Z}=\) atomic number of metal, \(\mathrm{X}=\) charge on metal, \(Y=\) electrons donated by ligand.)
