Question

Given below are two statements: Statement I: Crystal Field Stabilization Energy (CFSE) of [Cr(H2O)6] 2+ is greater than that of [Mn(H2O)6] 2+. Statement II: Potassium ferricyanide has a greater spin-only magnetic moment than sodium Ferrocyanide. In the light of the above statements, choose the correct answer from the options given below:

(A) Both Statement I and Statement II are true
(B) Both Statement I and Statement II are false
(C) Statement I is true but Statement II is false
(D) Statement I is false but Statement II is true

Correct answer: A. [Mn(H2O)6] 2+  CFSE value is zero because of d configuraiton with WFL in coordination number 6 [Cr(H2O)6] 2+. [Cr(H2O)6] 2+  CFSE value is –0.60 because of d configuraiton with WFL in coordination number 6. For : K3[Fe(CN)6] , µ 1(1 2) 3 B.M.    For : Na4[Fe(CN)6] , µ 0 B.M. 
