Why does Ga (+1) undergo disproportionation reaction?

Why does Mn(III) undergo disproportionation reaction easily ?

Explain why Ga(+1) undergoes disproportionation reaction.

Give reaction for the following : (a) In (III) is more stable than in (I) in aqueous solution. (b) InCl_(3) undergoes disproportionation but InCl does not. ( c) Unlike In^(oplus), Tl^(oplus) is more stable with respect to disproportionation. (d) Ga^(oplus) undergoes disproportionation reaction.
