`[CoF_(6)]^(3-)` forms outer orbital complexes while `(Co(CN)_(6)]^(3-)`forms inner orbital complexes. Why

Which is outer orbital complex?

Explain [Co(NH_3)_6]^(3+) is an inner orbital complex whereas [Ni(NH_3)_6]^(2+) is an outer orbital complex.

The complex ion [Fe(CN)_(6)]^(4-) contains:

How many of the following complexes are correctly matched with given properties ? (a) [Ni(NH_3)_6]^(2+) -Octahedral outer orbital complex and two unpaired electrons. (b) [Cr (NH_3)_6]^(3+) -Octahedral inner orbital complex and one unpaired electron. ( c) [Zn(NH_3)_6]^(2+) -Octahedral outer orbital complex and diamagnetic. (d) [Pt (NH_(3))_4]^(2+) -Square planar and diamagnetic (e) [Co (SCN)_4]^(2-) -Tetrahedral and three unpaired electrons. (f) [NiBr_2(PPh_3)_2] -Square planar and diamagnetic.
