Cobalt ( II ) is stable in aqueous solution but in the presence of complexing reagents(strong field ligands) it is readily oxidised. why ?
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
As 3d 6 configuration has higher CFSE as compared to 3d 7 so it gets oxidised in presence of complexing reagent to easily have d 2 sp 3 hybridisation.
