    A) NO is an odd electron molecule

    B) It is a free radical and highly reactive

    C) It readily forms complexes with transition metal ions

    D) It can be prepared by heating\[N{{H}_{4}}N{{O}_{3}}\]at\[{{250}^{o}}C\]

    Correct Answer: D

    Solution :

    It can be prepared in the laboratory by reacting sodium, nitrite\[(NaN{{O}_{2}})\]with a reducing agent such as\[F{{e}^{2+}}\]in an acidic medium.\[N{{H}_{4}}N{{O}_{3}}\]on heating at\[{{250}^{o}}C\]gives\[{{N}_{2}}O\].
