A) \[HCHO\]
B) \[CO\]
C) \[{{C}_{2}}{{H}_{5}}N{{H}_{2}}\]
D) \[C{{H}_{3}}N{{H}_{2}}\]
Correct Answer: D
Solution :
It is methyl amine which, being basic, dissolves in dilute \[HCl\]. It with \[NaN{{O}_{2}}\]evolves nitrogen gas leaving behind methyl alcohol which has smell of wood-spirit. \[C{{H}_{3}}N{{H}_{2}}\xrightarrow{HCl}C{{H}_{3}}N{{H}_{2}}.HCl\] \[C{{H}_{3}}N{{H}_{2}}+HN{{O}_{2}}\xrightarrow{NaN{{O}_{2}}/HCl}\underset{+{{N}_{2}}\uparrow +{{H}_{2}}O}{\mathop{\underset{methyl\,alcohol}{\mathop{C{{H}_{3}}OH}}\,}}\,\]
