Out of Cof63- and Co(En)33+, Which One Complex is (I) Paramagnetic (Ii) More Stable (Iii) Inner Orbital Complex and (Iv) High Spin Complex (Atomic No. of Co = 27) - Chemistry

Question

Answer in Brief

Out of [CoF6]3- and [Co(en)3]3+, which one complex is
(i) paramagnetic
(ii) more stable
(iii) inner orbital complex and
(iv) high spin complex
(Atomic no. of Co = 27) 

Solution

Co (Z=27)=1s2 2s2 2p6 3s2 3p6 4s2 3d7

Co+3 =1s2 2s2 2p6 3s2 3p6 3d7 

F- is weak field ligand: 
[CoF6]3-

(i) [CoF6]3- is paramagnetic due to the presence of four unpaired electrons 

(ii) [Co(en)3]3+ is more stable due to chelation

(iii) [Co(en)3]3+ forms inner orbital complex (d2sp3)

(iv) [CoF6]3+ Forms high spin complex (sp3d2)

  Is there an error in this question or solution?
