The reaction of white phosphorus iwht aqueous `NaOH` gives phosphine along with another phosphorus containing compund. The oxidation states of phosphorus in phosphine and the other product are respectively

Options

A. redox reaction,-3 and -5
B. redox reaction,+3 and +5
C. disproportionation reactions,-3 and +5
D. disproportionation reaction, -3 and+3

Explanation

(None is correct)
white phosphorus reacts with NaOH in an inert atmosphere as follows :
`P_(4)+3NaOH+3H_(2)Orarr3NaH_(2)PO_(2) +PH_(3)`
O.S of P in `NaH_(2)PO_(2),+1+2(+1)+x+2(-2)=0`
or x+3-4=0, x==4-3=+1
O.S of P in `PH_(3),x+3(+1)=0,x=-3`
The values donot match with any of choices given in the various options.This means that none of the options is correct.
