Question:
The geometry of $ Ni(CO)_{4}$ and $ Ni(PPh_{3})_{2}Cl_{2}$ are:
The geometry of $ Ni(CO)_{4}$ and $ Ni(PPh_{3})_{2}Cl_{2}$ are:
Updated On: Jun 7, 2022
- both square planar
- tetrahedral and square planar respectively
- both tetrahedral
- square planar and tetrahedral respectively
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
$Ni ( CO )_{4}$ and $Ni \left( PPh _{3}\right)_{2} Cl _{2}$ are tetrahedral in geometrical shape, because co-ordination number of $Ni$ is 4 in both cases.

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
