Choose the disprotionation reaction among the following redox reaction

1.	Choose the disprotionation reaction among the following redox reactions
Answer» `3 Mg (s) N_(2)(g)rarrMg_(3)N_(2)(s)` `P_(4)(s)+3NaOH(aq)+3H_(2)O(l)rarrPH_(3)(g)+3NaH_(2)PO_(2)(aq)` `CI_(2)(g)+2KI(aq)rarr2KCI(Aq)+I_(2)(s)` `Cr_(2)O_(3)(s)+2AI(s)rarrAI_(2)O_(3)(s)+2cr` SOLUTION :In reaction (b) `P_(4)` is both reduced to `PH_(3)` and oxidised to `NaH_(2)PO_(2)` thus it is a DISPROPORTION nation reaction butin all other redox reaction different speiced are oxidised / reduced i.e in reactoin(a) Mg is oxidised but `N_(2)` is reduced reaction (c ) `COI_(2)`is reduced AI is oxidised while in reaction (e ) `NA^(+)` is reduced but `H^(-)` oxidised
