    Which of the following compounds does not give nitrogen gas on heating -

    A) \[N{{H}_{4}}N{{O}_{2}}\]             

    B)  \[{{(N{{H}_{4}})}_{2}}S{{O}_{4}}\]

    C) \[N{{H}_{4}}Cl{{O}_{4}}\]            

    D)  \[{{(N{{H}_{4}})}_{2}}C{{r}_{2}}{{O}_{7}}\]

    Correct Answer: B

    Solution :

    [a] \[N{{H}_{4}}N{{O}_{2}}\xrightarrow[{}]{\Delta }{{N}_{2}}+2{{H}_{2}}O\] [b] \[{{(N{{H}_{4}})}_{2}}S{{O}_{4}}\xrightarrow[{}]{\Delta }N{{H}_{3}}+{{H}_{2}}S{{O}_{4}}\] [c] \[2N{{H}_{4}}Cl{{O}_{4}}\xrightarrow[{}]{\Delta }{{N}_{2}}+C{{l}_{2}}+2{{O}_{2}}+4{{H}_{2}}O\] [d] \[{{(N{{H}_{4}})}_{2}}C{{r}_{2}}{{O}_{7}}\xrightarrow[{}]{\Delta }{{N}_{2}}+C{{r}_{2}}{{O}_{3}}+4{{H}_{2}}O\]
