What are the geometry and magnetic behaviors of the complex \left[Ni{\left(CO\right)}_{4}\right]??What are the geometry and magnetic behaviors of the complex [Ni (CO) _ 4 ] ?What are the geometry and magnetic behaviors of the complex [Ni (CO) _ 4 ] ?

Options

  1. ASquare planar geometry and paramagnetic.
  2. BTetrahedral geometry and diamagnetic.
  3. CSquare planar geometry and diamagnetic.
  4. DTetrahedral geometry and paramagnetic.

Correct answer

B. Tetrahedral geometry and diamagnetic.

Step-by-step solution

Electronic configuration of:

Ni→3d84s2Ni \to 3{d}^{8}4{s}^{2}

What are the geometry and magnetic behaviors of the complex [Ni (CO) _ 4 ] ?

COCO is strong field ligand so unpaired electrons will get paired.
