The oxidation sate of phosphorus in hypophosphoric acid is

Correct answer

4

Step-by-step solution

Hypophosphoric acid H 4 P 2 O 6 The oxidation state of phosphorus is ⇒   4   ×   1   +   2   ×   x   +   6   ×   - 2   =   0 ⇒   4   +   2 x   -   12   =   0   ⇒   2 x   -   8   =   0 ⇒   2 x   =   8 ⇒   x   =   8 2   =   4
