Question

Why does mn (iii) undergoes disproportionantion reaction easily?

Answer 1

Reaction is not possible because mn is having its highest oxidation state and it cannot go further or say oxidation and only reduction possible so .so the d reaction requires oxidation number which and go oxidation as well as reduction.so the d reaction not possible.

Answer 2

Answer:

Since, +2 oxidation state is more stable as compared to +3 oxidation state due to stable half filled electronic configuration, therefore Mn(III) disproportionates to Mn(II).
