A) meta-formaldehyde
B) para-formaldehyde
C) urotropine
D) none of the above
Correct Answer: C
Solution :
Key Idea: Formaldehyde reacts with NH3 to form urotropine which is used as medicine to cure urinary infections. \[\underset{formaldehyde}{\mathop{6\,\,HCHO}}\,+\underset{ammonia}{\mathop{4N{{H}_{3}}}}\,\xrightarrow{{}}\underset{\begin{smallmatrix} hexamethylene \\ tetramine\text{ }or\text{ }urotropine \end{smallmatrix}}{\mathop{{{(C{{H}_{2}})}_{6}}N{{H}_{4}}}}\,\] \[\underset{\begin{smallmatrix} (h) \\ formaldehyde \end{smallmatrix}}{\mathop{HCHO}}\,\xrightarrow{37\,\,K}\underset{paraformaldehyde}{\mathop{{{(C{{H}_{2}}O)}_{n}}\,{{N}_{4}}}}\,\] \[\therefore \] [c] is the correct answer.You need to login to perform this action.
