$D$

Vedclass · Answer

(D) The given reaction is $P_4 + 3NaOH + 3H_2O \longrightarrow PH_3 + 3NaH_2PO_2$.In this reaction,the oxidation state of phosphorus $(P)$ changes from $0$ in $P_4$ to $-3$ in $PH_3$ and $+1$ in $NaH_2PO_2$.Since the same element is simultaneously oxidized and reduced,this is a disproportionation reaction.None of the categories $A$,$B$,or $C$ describe a redox reaction of this type.Therefore,the correct assignment is $D$ (no reaction among the given categories).
