White phosphorus reacts with caustic sod...

White phosphorus reacts with caustic soda to form `PH_(3)` and `NaH_(2) PO_(2)`. This reaction is an example of

A

oxidation

B

reduction

C

disproportionation

D

displacement

Text Solution

Verified by Experts

The correct Answer is:
C
`overset(0)P+3NaOH+3H_(2)Orarr3NaH_(2)overset(+1)PO_(2)+overset(-3)PH_(3)`
`overset(0)PrarrNaH_(2)overset(+1)PO_(2)` (Oxidation)
`overset(0)Prarr overset(-3)PH_(3)` (Reduction)
Simultaneous oxidation and reduction is disproportionation.
