A dark brown solid $(X)$ reacts with $NH_{3}$ to form a mild explosive which decomposes to give a violet coloured gas. $(X)$ also reacts with $H_{2}$ to give an acid $(Y).\ (Y)$ can also be prepared by heating its salt with $H_{3}PO_{4}.X\ and\ Y\ are$

(d)
$X = I_{2},Y = HI$
$3I_{2} + 2NH_{3} \rightarrow NH_{3} \bullet NI_{3}$
(explosive)
$8NI_{3} \bullet NH_{3} \rightarrow 5N_{2} + I_{2} + 6NH_{4}I$
$I_{2} + H_{2} \rightarrow 2HI$
$(Y)$
$3NaI + H_{3}PO_{4}\overset{\mathrm{\Delta}}{\rightarrow}\ Na_{3}PO_{4} + 3HI$
