Question

The reaction of P4 with X leads selectively to P4O6. The X is (A) dry O2 (B) a mixture O2 and N2 (C) moist O2 (D) O2 in the presence of aqueous NaOH

Tardigrade Admin · Accepted Answer

When phosphorous is burnt in limited supply of air, formation of P4O6 occur. ∵ P4 +air -> P4O6 ∴ P4 +3O2 + N2 -> P4O6 +N2 Nitrogen is used here to retard the further oxidation.

Q. The reaction of $P_{4}$ with X leads selectively to $P_{4} O_{6}$ . The X is

dry $O_{2}$

a mixture $O_{2}$ and $N_{2}$

moist $O_{2}$

$O_{2}$ in the presence of aqueous NaOH

When phosphorous is burnt in limited supply of air, formation of $P_{4} O_{6}$ occur.
$∵ P X_{4} + air P X_{4} O X_{6}$
$∴ P X_{4} + 3 O X_{2} + N X_{2} P X_{4} O X_{6} + N X_{2}$
Nitrogen is used here to retard the further oxidation.
