Hint: This reaction requires less supply of oxygen. So, some other element will be used that will competitively inhibit the full supply of oxygen. Complete step by step answer:For this, first, we will see the reaction of formation of ${P_4}{O_6}$.${P_4} + 3{O_2}\xrightarrow[{{N_2}}]{{{O_2}}}{P_4}{O_6}$Phosphorus trioxide is prepared by heating phosphorus in a limited supply of oxygen and nitrogen.Oxygen supply is provided in a limited quantity because if it is in more quantity then ${P_4}{O_6}$ will further oxidize to ${P_4}{O_6}$.Thus, option b.) is the correct answer.Additional information:Phosphorus exists in two major forms – white phosphorus and red phosphorus.Phosphorus is highly reactive. So, it is never found as a free element. Many oxides of phosphorus are formed in nature.Phosphorus trioxide is a colourless solid. It is the anhydride of phosphoric acid. So, in reaction with water, we get phosphorous acid.It is a good ligand for transition metals.Further, low temperature is required during its formation.Phosphorus trioxide is found to have a tetrahedral point group. This was determined from electron diffraction data.It consists of P – O – P bonds as well.Note:Nitrogen when present along with oxygen limits its supply so that further oxidation can be prevented. Absence of nitrogen will give a complete supply of oxygen and this can lead to oxidation of the product further.
