Question

[Pd(F)(Cl)(Br)(I)]^2– has n number of geometrical isomers. Then, the spin-only magnetic moment and crystal field stabilisation energy [CFSE] of [Fe(CN)₆]^n–6, respectively, are: 

[Note : Ignore the pairing energy] 

(1) 2.84 BM and –1.6 Δ0 

(2) 1.73 BM and –2.0 Δ0 

(3) 0 BM and –2.4 Δ0 

(4) 5.92 BM and 0

Answer 1

Answer is (2)

[Pb(F)(Cl)(Br)(I)]^2– have three geometrical isomer so formula for [Fe(CN)₆]^n–6 is [Fe(CN)₆]^3– and CFSE for this complex is

Answer 2

Answer is (2)
