- A \(2\)
- B \(8\)
- C \(6\)
- D \(4\)
Answer & Solution
Correct Answer
(A) \(2\)
Step-by-step Solution
Detailed explanation
\(Z=29( Cu )\) \(Cu ^{2+}\) form \(\left[ Cu \left( H _{2} O \right)_{4}\right]^{2+}\) complex ion with \(H _{2} O.\) \(\left[ Cu \left( H _{2} O \right)_{4}\right]^{2+} \Rightarrow Cu ^{2+}[ Ar ] 3 d ^{9}, H _{2} O \rightarrow WFL\) number of unpaired \(e ^{-}=1\)…
