Reducing property propto no. of P-H bond H3PO2 contains maximum P-H bond, <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/539159f6560f2f3f6eb32d8f9c0ad125-.png" />

Q. Which of the following oxoacids of phosphorus has strongest reducing property?

H₄P₂O₇

H₃PO₃

H₃PO₂

H₃PO₄

Reducing property $\propto$ no. of $P - H$ bond
$H_{3} P O_{2}$ contains maximum $P - H$ bond,
