Arrange the following Cobalt complexes in the order of incresing Crystal Field Stabilization Energy (CFSE) value. Complexes :
Choose the correct option :
As we have learnt ,
The CFSE depends upon the nature of ligands if the metal cation is the same.
Also, cations having greater positive charge have a greater CFSE.
Thus, the given complexes can be arranged in order of their CFSE as
Hence, the correct answer is option (1)
