    \[Pb+\] concentrated\[HN{{O}_{3}}\]gives

    A) \[Pb{{(N{{O}_{3}})}_{4}}+N{{O}_{3}}\]         

    B)  \[Pb{{(N{{O}_{3}})}_{3}}{{N}_{2}}O\]

    C)                  \[Pb{{(N{{O}_{3}})}_{2}}+N{{O}_{2}}\]

    D)      \[~PbN{{O}_{3}}+NO\]

    Correct Answer: C

    Solution :

    \[HN{{O}_{3}}\]is the best solvent for lead and the reaction is follows: \[Pb+4HN{{O}_{3}}(conc.)\to Pb{{(N{{O}_{3}})}_{2}}+2N{{O}_{2}}+2{{H}_{2}}O\] Hence, the correct option is (c).
