Question

$N H_{3}$ reacts with a gas fumes produced when methanol is passed through $C u$ tube at $573 K$ . The compound obtained is polycyclic. How many rings does it contain= [X]. The number of nitrogen atoms it has = [Y]? Report your answer as X+Y.

Solution

Methanol on passing through $C u$ tube at $573 K$ gets converted to methanal.
Methanal and ammonia react to form urotropin, a molecule similar in structure with admantane.

Number of ring present in the structure is $3 = X$
Number of $N$ atoms in structure is $4 = Y$
