    Which of the following shows nitrogen with its increasing order of oxidation number?

    A) \[{{N}_{2}}O<NO<N{{O}_{2}}<NO_{3}^{-}<NH_{4}^{+}\]

    B) \[NH_{4}^{+}<{{N}_{2}}O<NO<N{{O}_{2}}<NO_{3}^{-}\]

    C) \[NH_{4}^{+}<{{N}_{2}}O<N{{O}_{2}}<NO_{3}^{-}<NO\]

    D) \[NH_{4}^{+}<NO<{{N}_{2}}O<N{{O}_{2}}<NO_{3}^{-}\]

    Correct Answer: B

    Solution :

    \[{{N}_{2}}O=+1,\,NO=+2,\,N{{O}_{2}}=+4,\,NO_{3}^{-}=+5,\,NH_{4}^{+}=-3\]Increasing order of oxidation state will be \[NH_{4}^{+}<{{N}_{2}}O<NO<N{{O}_{2}}<NO_{3}^{-}\]
