is strongly oxidising.
species, manganese (III) is strongly reducing while is strongly oxidising.
B
Cobalt(II) is stable in aqueous solution but in the presence of complexing reagents it is easily oxidised.
C
The 
configuration is very unstable in ions.
configuration is very unstable in ions.
D
None of these.
Text Solution
Verified by ExpertsThe correct answer is:
NOT AVAILABLE
is reducing as it involves change from 
to 
, the latter is more stable configuration 
.
Due to higher CFSE of 
in presence of ligands 
is easily oxidized.
The ionisation enthalpy involved in removing electron from 
is compensated by hydration or lattice enthalpy.
