The reaction of P(4) with X leads select...

The reaction of `P_(4)` with X leads selectively to `P_(4)O_(6)` The X is :

A

dry `O_2`

B

a mixture of `O_2` and `N_2`

C

moist `O_2`

D

`O_2` in the presence of aqueous NaOH

Text Solution

Verified by Experts

The correct Answer is:
B
`P_4+3O_2 to P_4O_6`
Nitrogen prevents further oxidation of `P_4O_6` to `P_4O_10`
`P_4` when treated with dry `O_2` gives `P_4O_6` and finally `P_4O_10`.
With moist oxygen , `P_4` gives `H_3PO_3`.
`P_4 + 3NaOH + 3H_2O to 3NaH_2PO_2 + PH_3`
