Question
Which one of the following is an outer orbital complex and exhibits paramagnetic behaviour?
Options
A.[Co(NH3)6]3+
B.[Ni(NH3)6]2+
C.[Zn(NH3)6]2+
D.[Cr(NH3)6]3+
Solution
[Ni(NH3)6]2+
Here in Ni2+ the configuration is
Hence it gives outer orbital octahedral complex which is paramagnetic
Here in Ni2+ the configuration is
Hence it gives outer orbital octahedral complex which is paramagnetic
