- ✓$K _3\left[ Cu ( CN )_4\right]$
- B$K _2\left[ Cu ( CN )_4\right]$
- C$K _3\left[ Fe ( CN )_4\right]$
- D$K _4\left[ FeCl _6\right]$
✓
Answer
Correct option: A.
$K _3\left[ Cu ( CN )_4\right]$
(A)$K _3\left[ Cu ( CN )_4\right]$
Explanation:
$K _3\left[ Cu ( CN )_4\right]$
O.N. of copper is $Cu ^{+}$
$Cu ^{+} \Rightarrow[ Ar ] 3 d^{10} \Rightarrow$ Diamagnetic
Explanation:
$K _3\left[ Cu ( CN )_4\right]$
