Question

Match 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 FeSO4, followed by acidification with conc. H2SO4, 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 NaHCO3 results in effervescence.
IV	Coprolactam	S	The compound reacts with bromine water to give a white precipitate
		T	Treating the compound with neutral FeCl3 solution produces violet color.

• A. I → P, Q; II → S; III → Q, R; IV → P
• B. I → P ; II → R, S; III → R; IV → Q, S
• C. I → Q, S; II → P, T; III → P; IV → S
• D. I → P, S; II → T; III → Q, R; IV → P

Answer 1

The Correct Option is D

: Blue colour in Lassign test due to presence of N

 

 

 

:Violet colour with FeCl₃ due to presence of phenolic OH

: It gives blood red colour with NaSCN

Caprolactam:
