Which one of the following is an inner orbital complex as well as diamagnetic in behaviour?
- A[Zn(NH3)6]2+
- B[Cr(NH3)6]3+
- C[Co(NH3)6]3+
- D[Ni(NH3)6]2+
View written solutionFree
Correct answer: C
In [Co(NH3)6]3+
Co+3 = [18Ar] 3d64s0

[Co(NH3)6]3+ is an inner orbital complex as well as diamagnetic in behaviour (due to absence of unpaired electrons).
