8.21 How would you account for the following:
(i) Of the species, is strongly reducing while manganese(III) is strongly oxidising.
is strongly reducing in nature. It has configuration. By losing one electron it gets oxidised to (electronic configuration ) which can be written as and it is a more stable configuration. On the other hand has also configuration by accepting one electron it gets reduced and act as strongly oxidising agent(electronic configuration ). Thus it is extra stable due to half -filled with d-orbital.
