Match List - I with List - II :
| List - I Name of oxo acid |
List - II Oxidation state of 'P' |
||
|---|---|---|---|
| (a) | Hypophosphorous acid | (i) | +5 |
| (b) | Orthophosphoric acid | (ii) | +4 |
| (c) | Hypophosphoric acid | (iii) | +3 |
| (d) | Orthophosphorous acid | (iv) | +2 |
| (v) | +1 |
Choose the correct answer from the options given below :
Solution
(a) Hypophosphorus acid : ${H_3}\underline P {O_2}$<br><br>
(+1) 3 + x + (–2)2 = 0<br><br>
x = +1<br><br>
(b) Orthophosphoric acid : ${H_3}\underline P {O_4}$<br><br>
(+1) 3 + x + (–2)4 = 0<br><br>
x = +5<br><br>
(c) Hypophosphoric acid : ${H_4}\underline {{P_2}} {O_6}$<br><br>
(+1) 4 + 2x + (–2)6 = 0<br><br>
x = +4<br><br>
(d) Orthophosphorous acid : ${H_3}\underline P {O_3}$<br><br>
(+1)3 + x + (–2)3 = 0<br><br>
x = +3
