What are the compounds formed when white Phosphorous is dissolved in boiling NaOH solution in an inert atmosphere ?

A

`PH_3 , NaPO_4`

B

`NaH_2PO_4 , P(OH)_3`

C

`PH_3 , NaH_2PO_2`

D

`P_4O_10,Na`

Text Solution

Verified by Experts

The correct Answer is:
C
White phosphorus dissolves in boiling NaOH solution (in a `CO_2` atmosphere) to give phosphinc `(PH_3)` and sodium hypo-phosphate `(NaH_2 PO_2 )` .
`P_4 + 3NaOH + 3H_2O to underset("Sodium hypo-phosphate")(PH_3 + 3NaH_2PO_2)`
