NEET Solved Paper 2018 Question 28
Question: The geometry and magnetic behaviour of the complex $ [\text{ Ni(CO}{{)}_4}] $ are [NEET - 2018]
Options:
A) Square planar geometry and paramagnetic
B) Tetrahedral geometry and diamagnetic
C) Square planar geometry and diamagnetic
D) Tetrahedral geometry and paramagnetic
Show Answer
Answer:
Correct Answer: B
Solution:
- $ \text{Ni(28): }[\text{ Ar }]\text{ 3}{d^{8}}4{s^{2}} $ $ \because CO $ is a strong field ligand Configuration would be : For, four ?CO?-ligands hybridisation would be $ s{p^{3}} $ and thus the complex would be diamagnetic and of tetrahedral geometry.
