Coordination Compounds 2 Question 52
####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)
$B \rightarrow p, r, s \quad C \rightarrow q, s \quad D \rightarrow q, s$
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 $Cl^{-}$.
Paramagnetic
