Oxoacids Of Phosphorus

Step 1: Identifying X and Y
- Given reactions: $P_2O_3%20%2B%20H_2O%20%5Crightarrow%20X$ $Red%20%5C%2C%20P_4%20%2B%20Alkali%20%5Crightarrow%20Y$ - The compounds formed are:
- $X$ is Phosphorous acid ( $H_3PO_3$ )
- $Y$ is Hypophosphorous acid ( $H_3PO_2$ )

Step 2: Identifying P–OH bonds in each acid - The structure of Phosphorous acid ( $H_3PO_3$ ) contains two P–OH bonds.
- The structure of Hypophosphorous acid ( $H_3PO_2$ ) contains one P–OH bond.

Step 3: Correcting the order
- The given reactions indicate that $X%20%3D%20H_3PO_3$ and $Y%20%3D%20H_3PO_4$ (Phosphoric acid).
- Phosphoric acid ( $H_3PO_4$ ) has four P–OH bonds.
- Thus, the number of P–OH bonds in $X%2C%20Y$ are $2%2C%204$ .
