View SolutionMatch the compounds in List-$I$ with the observations in List-$II$,and choose the correct option.
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.
