JEE Main & Advanced Chemistry Redox Reactions / रेडॉक्स अभिक्रियाएँ Question Bank Oxidation number and Oxidation state

  • question_answer
    \[HN{{O}_{2}}\] acts both as reductant and oxidant, while \[HN{{O}_{3}}\] acts only as oxidant. It is due to their                 [AIIMS  2000]

    A)                 Solubility ability

    B)                 Maximum oxidation number

    C)                 Minimum oxidation number

    D)                 Minimum number of valence electrons

    Correct Answer: B

    Solution :

           In \[\overset{*}{\mathop{HN{{O}_{2}}}}\,\] oxidation number of N = + 3                                 In \[\overset{*}{\mathop{HN{{O}_{3}}}}\,\] oxidation number of N = + 5.
