Q. White phosphorus on reaction with concentrated $NaOH$ solution in an inert atmosphere of $CO_{2}$ gives phosphine and compound $\left(\right.X\left.\right)$ . $\left(\right.X\left.\right)$ on acidification with $HCl$ gives compound $\left(\right.Y\left.\right)$ . The basicity of compound $\left(\right.Y\left.\right)$ is

Solution:

Here Hypophosphorus acid is formed as Y and its basicity is 1.
$P_{4}+NaOH+H_{2}O \rightarrow PH_{3}+NaH_{2}PO_{2}\overset{HCl}{ \rightarrow }H_{3}PO_{2}$
Solution
Basicity = 1
