Which statement is incorrect?a)Ni(CO)₄ : Tetrahedral, paramagnet...
Explanation :
In Ni(CO)4, Ni is in the zero oxidation state i.e., it has a configuration of 3d8 4s2.But CO is a strong field ligand. Therefore, it causes the pairing of unpaired 3d electrons. Also, it causes the 4s electrons to shift to the 3d orbital, thereby giving rise to sp3 hybridization. Since no unpaired electrons are present in this case, [Ni(CO)4] is diamagnetic.

Which statement is incorrect?a)Ni(CO)₄ : Tetrahedral, paramagnet...
Explanation:
There are multiple statements given about different nickel complexes, and we need to identify the incorrect one. Let's break down each statement and analyze them:
Statement a:
- Ni(CO) is a complex with carbon monoxide ligands.
- The coordination number of Ni(CO) is 4, which results in a tetrahedral geometry.
- The complex Ni(CO) is paramagnetic due to the presence of unpaired electrons.
Statement b:
- [Ni(CN)]2 is a complex with cyanide ligands.
- The coordination number of [Ni(CN)]2 is 4, which results in a square planar geometry.
- The complex [Ni(CN)]2 is diamagnetic because all electrons are paired.
Statement c:
- Ni(CO) is a complex with carbon monoxide ligands.
- The coordination number of Ni(CO) is 4, which results in a tetrahedral geometry.
- The statement that Ni(CO) is diamagnetic is incorrect because it should be paramagnetic.
Statement d:
- [NiCl]2 is a complex with chloride ligands.
- The coordination number of [NiCl]2 is 4, which results in a tetrahedral geometry.
- The complex [NiCl]2 is paramagnetic due to the presence of unpaired electrons.
Conclusion:
After analyzing all the statements, it is evident that statement a is incorrect. Ni(CO) is tetrahedral in geometry and paramagnetic, not diamagnetic.
