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

(B) P4 + 3O2 ?N2 P4O6 (exclusively) (N2 is used to retard the further oxidation.)

B

Hello Student

Phosphorus trioxide (P_4​O₆​) is prepared by heating phosphorus in the limited supply of oxygen and nitrogen.


N₂​prevents further oxidation of P_4​O₆​ to P_4​O₁₀​.

So option B is correct.

I hope this answer will help you.

Dear student,
Please find the attached answer to your question.

Phosphorus trioxide (P₄​O₆​) is prepared by heating phosphorus in the limited supply of oxygen and nitrogen. The nitrogen acts as a retarder and prevents the formation of P₄O₁₀
P₄ + 3O₂ + N₂ → P₄O₆ + N₂
(N₂ acts as a retarder)
Hence option B) is correct.

Hope it helps.
Thanks and regards,
