Chemistry - Coordination Chemistry Question with Solution | TestHub
The crystal field theory (CFT) is an electrostatic model, which considers the metal-ligand bond to be ionic, arising purely from electrostatic interactin between the metal ion and the ligand.
For complex then find sum of X + Y + Z (by considering C.F.T. only) X = Number of electron in t orbital of central metal atom Y = Value of spin only magnetic moment Z = Number of electron in e orbital of central metal atom.
Answer:
Solution:
To find the sum of for the complex :
Oxidation State & Configuration: The central metal ion is Co²⁺, which has a a electronic configuration.
Crystal Field Splitting: Since CN⁻ is a strong field ligand, pairing occurs, giving the configuration .
Values of X and Z: (electrons in orbital) and (electron in orbital).
Value of Y: With unpaired electron, the spin-only magnetic moment is , which rounds to for integer values.
Final Sum: Therefore, the sum is .
