    The set of oxidation numbers of nitrogen in ammonium nitrate is

    A)  \[-3,+3\]          

    B)  \[-1,+1\]

    C)  \[+1,-1\]          

    D)  \[-3,+5\]

    Correct Answer: D

    Solution :

     \[N{{H}_{4}}N{{O}_{3}}NH_{4}^{+}+NO_{3}^{-}\] Let the oxidation number of N is\[x\]. In \[NH_{4}^{+}\] \[x+4=1\] \[x=1-4=-3\] In \[NO_{3}^{-}\] \[x+3(-2)=-1\] \[x-6=-1\] \[x=-1+6\] \[=+5\] Hence, the set of oxidation number of nitrogen in ammonium nitrate is\[-3,+5\].
