Refer to the periodic table given in your book and now answer the following questions:
a. Select the possible non metals that can show disproportionation reaction.
b. Select three metals that can show disproportionation reaction.

Explanation

(a) `P+_(4)(s)+3OH^(-)(aq)+3H_(2)(l)rarrPH_(3)(g)+3H_(2)PO_(2)^(-)(aq)`
(ii) `CI_(2)(g)+2OH^(-)overset(cold)rarrCi^(-)(aq)+CIO^(-)(aq)+H_(2)O(l)`
or `3CI_(2)(g)+6OH^(-)(aq)overset(hot)rarr5CI^(-)(aq)+CIO_(3)^(-)(aq)+3H_(2)O(l)`
(iii) `S_(8)(s)+12OH^(-)rarr4S^(2-)(aq)+2S_(2)O_(3)^(2-)(aq)+6H_(2)O(l)`
(iii) `S_(8)(s)+12 OH^(-)rarr45S^(2-)(aq)+2S_(2)O_(3)^(2-)(aq)+6H_(2)O (l)`
(b) The metals are :`Cu^(+),Ga^(+),In^(+),Mn^(3+)`, etc
`2Cu^(+)(aq)rarrCu^(2+)(aq)+Cu^(s)`
`3Ga^(+)(aq)rarrGa^(3+)(aq)+2Ga(s)`
`3In^(+)(aq)rarrIn^(3+)(aq)+2In(s)`
