White $P_{4}$

Vedclass · Answer

(A) The reaction of white phosphorus $(P_{4})$ with an alkali (like $NaOH$) is a disproportionation reaction.The reaction is: $P_{4} + 3NaOH + 3H_{2}O \rightarrow PH_{3} + 3NaH_{2}PO_{2}$.However,the question specifies that $B$ is an oxoacid of phosphorus with no $P-H$ bond.When white phosphorus $(P_{4})$ reacts with oxygen,it forms $P_{4}O_{10}$.$P_{4}O_{10} + 6H_{2}O \rightarrow 4H_{3}PO_{4}$.$H_{3}PO_{4}$ (phosphoric acid) is an oxoacid of phosphorus that contains no $P-H$ bonds.Thus,$A$ is $P_{4}$ (white phosphorus) which undergoes oxidation to form $P_{4}O_{10}$,followed by hydrolysis to form $H_{3}PO_{4}$.

Consider the following reaction:
$A +$ alkali $\rightarrow B$ (Major Product)
If $B$ is an oxoacid of phosphorus with no $P-H$ bond,then $A$ is ..... .
