Co-Ordination Compounds Question 241
Question: For octahedral complex, which of the following $ d^{n} $ configurations of metal cation cannot exist in high spin and low spin forms?
Options:
A) $ d^{3} $ and $ d^{8} $
B) $ d^{3} $ and $ d^{5} $
C) $ d^{3} $ and $ d^{6} $
D) $ d^{4} $ and $ d^{8} $
Show Answer
Answer:
Correct Answer: A
Solution:
In $ d^{3} $ and $ d^{8} $ octahedral complexes number of unpaired $ {e^{-}} $ s at central metal atom/ion never changes, therefore for such octahedral complexes terms high spin and low spin not used.
