Coordination Compounds 2 Question 52
Passage Based Questions
The coordination number of $Ni^{2+}$ is $4$ .
$NiCl _2+KCN$ (excess) $\longrightarrow A$ (cyano complex)
$NiCl _2+$ conc. $HCl$ (excess) $\longrightarrow B$ (chloro complex)
54. Predict the magnetic nature of $A$ and $B$.
(a) Both are diamagnetic
(b) $A$ is diamagnetic and $B$ is paramagnetic with one unpaired electron
(c) $A$ is diamagnetic and $B$ is paramagnetic with two unpaired electrons
(d) Both are paramagnetic
Show Answer
Answer:
Correct Answer: 54. (c)
Solution:
- $A$ is diamagnetic, square planar complex because of strong ligand field of $CN^{-}$.
$B$ is paramagnetic, tetrahedral complex because of weak ligand field of $Cl^{-}$.
