Question

In which of the following species, the oxidation number of the atom of the underlined elements is/are equal to +1?

विकल्प

• \[\ce{\underline{S}_2O^{2-}3, \underline{P}_3O^{3-}9}\]

• \[\ce{\underline{P}_3O^{3-}9, \underline{N}_2O}\]

• \[\ce{\underline{H}_3PO_2, \underline{Fe}_2O_3}\]

• \[\ce{\underline{N}_2O, H_3\underline{P}O_2}\]

Answer 1

\[\ce{\underline{N}_2O, H_3\underline{P}O_2}\]

Explanation:

\[\ce{\underline{N}_2O}\]

2x – 2 = 0

⇒ x = +1

\[\ce{H3\underline{P}O2}\]

3 (1) + x + 2 (–2) = 0

⇒ x = 4 – 3 = +1
