The reaction of white phosphorus with aqueous NaOH gives phosphine along with another compound. The reaction type , the oxidation states of phosphorus in phosphine and the other product are respectively

Answer»

redox reaction , -3 and -5
redox reaction , +3 and +5
disproportionation reaction , -3 and -5
disproportionation reaction , -3 and +1

SOLUTION :`overset(0)(P_(4))+3NaOH + 3H_(2)O RARR 3NaH_(2) overset(+1)(PO_(2))+overset(-3)(PH_(3))`
It is a disproportionation reaction. In this reaction, oxidation state of P increases from 0 in `P_(4)` to +1 in `NaH_(2)PO_(2)` and decreases from 0 in `P_(4)` to -3 in `PH_(3)`.
