Coordination Compounds 2 Question 36
####38. Both $\left[Ni(CO) _4\right]$ and $\left[Ni(CN) _4\right]^{2-}$ are diamagnetic. The hybridisations of nickel in these complexes respectively, are
(a) $s p^{3}, s p^{3}$
(b) $s p^{3}, d s p^{2}$
(c) $d s p^{2}, s p^{3}$
(d) $d s p^{2}, d s p^{2}$
$(2008,3 M)$
Show Answer
Answer:
Correct Answer: 38. (b)
Solution:
- In $Ni(CO) _4, Ni$ is $s p^{3}$-hybridised while in $\left[Ni(CN) _4\right]^{2-}, Ni^{2+}$ is $d s p^{2}$-hybridised.
