Identify the correct statements with reference to the given reaction
`P_(4)+3OH^(-)+3H_(2)OtoPH_(3)+3H_(2)PO_(2)^(-)`

Options

A. Phosphorus undergoing reduction only
B. Phosphorus in undergoing oxidation only
C. Phosphorus is undergoing oxidation as well as reduction.
D. Hydrogen is undergoing neither oxidation nor reduction

Answer

C, D

Explanation

`overset(0)(P_4)+3overset(-2+1)(OH^(-))rarr3overset(+1-2)(H_2O)rarroverset(-3+1)(PH_3) +3H_2PO_2^(-)`
Because O. N of O increases form 0 `(P_4)` to +1 `(H_2PO_2^(-))` and decreases from `0(P_4)` tp -3 `(PH_3)` , therefore , P has undergone both oxidation as well as reduction . Option (c) is correct (c) is correct . Option (d) is also correct because O.N. of H remains +1 in all the compounds and hence hydrogen is undergoing neither oxidatin nor reduction.
