The correct answer is [E] NO\u2082<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

The oxidation state of an element in a compound is determined by assigning charges based on specific rules, such as assigning -2 for oxygen (in most cases) and +1 for hydrogen. Let us calculate the oxidation state of nitrogen in each of the given compounds:<\/p>\n\n\n\n

\n\n\n\n

[A] NH\u2084Cl (Ammonium chloride):<\/strong><\/p>\n\n\n\n

    \n
  • The ammonium ion ((NH_4^+)) has a net charge of +1.<\/li>\n\n\n\n
  • Hydrogen ((H)) has an oxidation state of +1.<\/li>\n\n\n\n
  • Let (x) be the oxidation state of nitrogen:
    [
    x + 4(+1) = +1 \\implies x = -3
    ]
    Nitrogen in (NH_4Cl) has an oxidation state of (-3).<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    [B] HNO\u2083 (Nitric acid):<\/strong><\/p>\n\n\n\n

      \n
    • Oxygen ((O)) has an oxidation state of -2, and there are three oxygen atoms.<\/li>\n\n\n\n
    • Hydrogen ((H)) has an oxidation state of +1.<\/li>\n\n\n\n
    • Let (x) be the oxidation state of nitrogen:
      [
      x + 1 + 3(-2) = 0 \\implies x – 5 = 0 \\implies x = +5
      ]
      Nitrogen in (HNO_3) has an oxidation state of (+5).<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      [C] NaNO\u2082 (Sodium nitrite):<\/strong><\/p>\n\n\n\n

        \n
      • Sodium ((Na)) has an oxidation state of +1, and oxygen is -2.<\/li>\n\n\n\n
      • Let (x) be the oxidation state of nitrogen:
        [
        1 + x + 2(-2) = 0 \\implies x – 3 = 0 \\implies x = +3
        ]
        Nitrogen in (NaNO_2) has an oxidation state of (+3).<\/li>\n<\/ul>\n\n\n\n
        \n\n\n\n

        [D] N\u2082O (Dinitrogen monoxide):<\/strong><\/p>\n\n\n\n

          \n
        • Oxygen is -2. Let (x) be the oxidation state of nitrogen:
          [
          2x + (-2) = 0 \\implies 2x = 2 \\implies x = +1
          ]
          Each nitrogen atom in (N_2O) has an oxidation state of (+1).<\/li>\n<\/ul>\n\n\n\n
          \n\n\n\n

          [E] NO\u2082 (Nitrogen dioxide):<\/strong><\/p>\n\n\n\n

            \n
          • Oxygen is -2, and there are two oxygen atoms.<\/li>\n\n\n\n
          • Let (x) be the oxidation state of nitrogen:
            [
            x + 2(-2) = 0 \\implies x – 4 = 0 \\implies x = +4
            ]
            Nitrogen in (NO_2) has an oxidation state of (+4).<\/li>\n<\/ul>\n\n\n\n
            \n\n\n\n

            Thus, the correct answer is [E] NO\u2082<\/strong>, where nitrogen has an oxidation state of (+4).<\/p>\n","protected":false},"excerpt":{"rendered":"
