Which one of the following is an inner orbital complex as well as diamagnetic in nature?A. (a) `[Cr(NH_3)_6]^(3+)`B. (b) `[Co(NH_3)_6]^(3+)`C. (c) `[Ni(NH_3)_6]^(2+)`D. (d) `[Zn(NH_3)_6]^(2+)` |

Answer» Correct Answer - B In `[Zn(NH_3)_6]^(3+)`, `Zn` exists as `Zn^(2+) ._(30)Zn: 3d^(10), 4s^2` `Zn^(2+): 3d^(10)`. Thus, no unpaired electron but it is outer orbital complex. In `[Co(NH_3)_6]^(3+)`, Co exists as `Co^(3+)` `._(27)Co:3d^7, 4s^2` `Co^(3+): 3d^(6)`, It is `d^2 sp^3` inner orbital complex with no unpaired `e^(-)` in `3d` due to forced pairing. |
