Which of the following complex is not correctly matched with it's geom...
Incorrect Match: [Co(py)]2- - Square planar
Explanation:
Tetrahedral Geometry:
- Tetrahedral geometry is a shape in which four atoms or groups of atoms are arranged symmetrically around a central atom, forming a tetrahedron.
- The central atom is bonded to four other atoms or groups of atoms, with bond angles of approximately 109.5 degrees.
- The coordination number is 4.
Square Planar Geometry:
- Square planar geometry is a shape in which four ligands or groups of atoms are arranged around a central metal atom in a flat square plane.
- The central atom is bonded to four other atoms or groups of atoms, with bond angles of 90 degrees.
- The coordination number is 4.
Analysis:
a) [NiCl2(Ph3P)2]-tetrahedral
- In this complex, the nickel atom is bonded to two chloride ions and two triphenylphosphine (Ph3P) ligands.
- The coordination number is 4, and the arrangement of ligands around the central atom is tetrahedral.
- This complex is correctly matched with its geometry.
b) [Co(py)]2- - Square planar
- In this complex, the cobalt atom is bonded to one pyridine (py) ligand.
- The coordination number is 4, but the arrangement of ligands around the central atom is incorrectly given as square planar.
- The correct geometry for this complex is tetrahedral, as it has one ligand and three vacant coordination sites.
- Therefore, this complex is not correctly matched with its geometry.
c) [Cu(CN)2]³- -tetrahedral
- In this complex, the copper atom is bonded to two cyanide (CN) ligands.
- The coordination number is 4, and the arrangement of ligands around the central atom is tetrahedral.
- This complex is correctly matched with its geometry.
d) [Fe(CO)4]²- -square planar
- In this complex, the iron atom is bonded to four carbonyl (CO) ligands.
- The coordination number is 4, and the arrangement of ligands around the central atom is correctly given as square planar.
- This complex is correctly matched with its geometry.
Conclusion:
The complex [Co(py)]2- is not correctly matched with its geometry. It should be tetrahedral, not square planar.
