question_answer

Both\[HCHO\]and\[C{{H}_{3}}CHO\]gives similar reactions with all the reagents except

A)  Schiff reagent

B)                         Fehling solution

C)                         ammoniacal\[AgN{{O}_{3}}\]

D)                         ammonia

Correct Answer: D

Solution :

\[HCNO\]and\[C{{H}_{3}}CHO\]give different reactions with\[N{{H}_{3}}\]. \[\underset{formaldehyde}{\mathop{6HCHO+4N{{H}_{3}}}}\,\xrightarrow{{}}\underset{Urotropine}{\mathop{{{(C{{H}_{2}})}_{6}}{{N}_{4}}}}\,+6{{H}_{2}}O\]
