The reaction of white phosphorus on boiling with alkali in inert atmosphere resulted in the formation of product

A .

The reaction

1mol

A

with excess of

{AgNO}_{3}

in aqueous medium gives ________ mole(s)

of Ag .

(Round off to the Nearest Integer).

Correct answer

Step-by-step solution

${P}_{4} + 3{OH}^{-} + 3{H}_{2}O \to {PH}_{3} + \mathop{3{H}_{2}{PO}_{2}^{-}}_{\left(A\right)}$

$\mathop{{H}_{2}{PO}_{2}^{-}}_{1\text{mole}} + \mathop{4{Ag}^{+}}_{\text{excess}} + 2{H}_{2}O \to \mathop{{H}_{3}{PO}_{4} + 4Ag + 3{H}^{+}}_{4\text{mole}}$
