- A \(\left[ Zn \left( H _2 O \right)_6\right]^{2+}\)
- B \(\left[ Co \left( H _2 O \right)_6\right]^{2+}\)
- C \(\left[ Co ( en )_3\right]^{3+}\)
- D \(\left[ Ni \left( H _2 O _6\right]^{2+}\right.\)
Answer & Solution
Correct Answer
(B) \(\left[ Co \left( H _2 O \right)_6\right]^{2+}\)
Step-by-step Solution
Detailed explanation
Complex with maximum number of unpaired electron will exhibit maximum attraction to an applied magnetic field \({\left[ Zn \left( H _2 O \right)_6\right]^{2+} \rightarrow d ^{10} \text { system } \rightarrow t _{2 g }^6 eg ^4, 0 \text { unpaired } e ^{-}}\)…
