The gas  and dibasic acid are, respectively,

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

B)        \[{{N}_{2}}O,\,{{H}_{2}}{{N}_{2}}{{O}_{2}}\]    

C)      \[{{N}_{2}}\,{{H}_{2}}{{N}_{2}}O\]       

D)        \[NO,\,\,{{H}_{2}}{{N}_{2}}{{O}_{3}}\]

Correct Answer: B

Solution :

[b] \[N{{H}_{4}}N{{O}_{3}}\xrightarrow{\Delta }\underset{(A)\,(gas)}{\mathop{{{N}_{2}}O}}\,+\underset{(B)}{\mathop{2{{H}_{2}}O}}\,\] \[\underset{(A)}{\mathop{{{N}_{2}}O}}\,+\underset{(B)}{\mathop{{{H}_{2}}O}}\,\xrightarrow{{}}\underset{\text{Hypointrous acid}}{\mathop{{{H}_{2}}{{N}_{2}}{{O}_{2}}}}\,\]
