Arrange the following coordination compounds in the increasing order of magnetic moments. (Atomic numbers : Mn = 25; Fe = 26)

A. [FeF6]3−

B. [Fe(CN)6]3−

C. [MnCl6]3− (high spin)

D. [Mn(CN)6]3−

Choose the correct answer from the options given below :

Multiple Choice Options

  • A A < B < D < C
  • B B < D < C < A
  • C A < C < D < B
  • D B < D < A < C

Step-by-Step Verified Solution

Coordination Compound Number of unpaired e– (n) Magnetic moment (µ) (B.M)
A. [FeF6]3− - d5 5 5.91
B. [Fe(CN)6]3− - d5 1 1.73
C. [MnCl6]3− - d4 4 4.89
D. [Mn(CN)6]3− - d4 2 2.82

Hence, correct order of magnetic moment is 2 &lt; 4 &lt; 3 &lt; 1
