$(X)$ and $(Y)$ will respectively be :

| $LIST-I$ | $LIST-II$ |
| $(I)$ Aniline | $(P)$ Sodium fusion extract of the compound on boiling with $FeSO _4$, followed by acidification with conc. $H _2 SO _4$, gives Prussian blue color. |
| $(II)$ o-Cresol | $(Q)$ Sodium fusion extract of the compound on treatment with sodium nitroprusside gives blood red color. |
| $(III)$ Cysteine | $(R)$ Addition of the compound to a saturated solution of $NaHCO _3$ results in effervescence. |
| $(IV)$ Coprolactam | $(S)$ The compound reacts with bromine water to give a white precipitate. |
| $(T)$ Treating the compound with neutral $FeCl _3$ solution produces violet color. |
