List-$I$	List-$II$
$I$. Aniline	$P$. Sodium fusion extract of the compound on boiling with $FeSO_4$,followed by acidification with conc. $H_2SO_4$,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.
$IV$. Caprolactam	$S$. The compound reacts with bromine water to give a white precipitate.
	$T$. Treating the compound with neutral $FeCl_3$ solution produces violet color.
