If an iron \((III)\) complex with the formula \(\left[\mathrm{Fe}\left(\mathrm{NH}_3\right)_{\mathrm{X}}(\mathrm{CN})_{\mathrm{Y}}\right]^{-}\)has no electron in its \(\mathrm{e}_{\mathrm{g}}\) orbital, then the value of \(x+y\) is _______.
- A \(5\)
- B \(6\)
- C \(3\)
- D \(4\)
Answer & Solution
Correct Answer
(B) \(6\)
Step-by-step Solution
Detailed explanation
Complex is\(\left[\mathrm{III}\left(\mathrm{NH}_3\right)_2(\mathrm{CN})_4\right]^{\Theta}\) \( x=2\) \(y=4\) \(\text { so } x+y=6\)
