Given below are two statements : Statement I : Crystal Field Stabilization Energy (CFSE) of [ Cr ( H _ 2 O )_ 6 ]^ 2+ is greater than that of [ Mn ( H _ 2 O )_ 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
[ Mn ( H _2 O )_6 ]^ 2+ CFSE value is zero because of d ^5 configuration with Weak Field Ligands in coordination number 6 [ Cr ( H _2 O )_6 ]^ 2+ . [ Cr ( H _2 O )_6 ]^ 2+ CFSE value is -0.6 _0 because of d ^4 configuration with Weak Field Ligands in coordination number 6. For : K _3 [ Fe ( CN )_6 ], = 1(1+2) = 3 B.M. For : Na _4 [ Fe ( CN )_6 ], = 0 B.M.
