Which one of the following is an inner orbital complex as well as diamagnetic in behaviour ?(Atomic no.: Zn=30,Cr=24 Co=27,Ni=28)
A
[Zn (NH3)6]2+
B
[Cr (NH3)6]3+
C
[Co (NH3)6]3+
D
[Ni (NH3)6]2+
Answer
[Co (NH3)6]3+
Explanation
Solution
[Co(NH3)6] In addition to having an inner orbital complex, 3+ exhibits diamagnetic properties.
Therefore, the correct option is (C): [Co (NH3)6]3+
