Phosphorus forms a number of oxoacids which differ in their structures and oxidation state of phosphorus. All the acids contain phosphorus atom//atoms linked tetrahedrally to four other atoms or groups. Each of them has at least one `P=O` or `P rarr O` unit and one `P-OH` unit. The `OH` group is ionisable but `H` atom linked directly to `P` is non-ionisabl. Structures of all the acids are considered to be derived either from phosphorus acid or phosphoric acid. The number of or `P = O` and `P - O- H` bonds in `H_3 PO_4` are.A. `3, 1`B. `2, 2`C. `1, 2`D. `1, 3`

1.	Phosphorus forms a number of oxoacids which differ in their structures and oxidation state of phosphorus. All the acids contain phosphorus atom//atoms linked tetrahedrally to four other atoms or groups. Each of them has at least one `P=O` or `P rarr O` unit and one `P-OH` unit. The `OH` group is ionisable but `H` atom linked directly to `P` is non-ionisabl. Structures of all the acids are considered to be derived either from phosphorus acid or phosphoric acid. The number of or `P = O` and `P - O- H` bonds in `H_3 PO_4` are.A. `3, 1`B. `2, 2`C. `1, 2`D. `1, 3`
Answer» Correct Answer - D Number of `P = 0 bonds = 1` Number of `P - OH bonds = 3`.
