List - IList - II
(P)
(1) Reaction with phenyl diazonium salt gives #ff0 dye.
(Q)
(2) Reaction with ninhydrin gives purple color and it also reacts with \(FeCl _3\) to give violet color.
(R)
(3) Reaction with glucose will give corresponding hydrazone.
(S)
(4) Lassiagne extract of the compound treated with dilute HCl followed by addition of aqueous \(FeCl _3\) gives blood red color.
(5) After complete hydrolysis,it will give ninhydrin test and it DOES NOT give positive phthalein dye test.

Answer & Solution

Correct Answer

(B) \(\mathrm{P} \rightarrow 2 ; \mathrm{Q} \rightarrow 5 ; \mathrm{R} \rightarrow 1 ; \mathrm{S} \rightarrow 3\)

Step-by-step Solution

Detailed explanation

(P)

Gives \(\mathrm{FeCl}_3\) test because of presence of phenolic group and ninhydrin test.
(Q)

Amino acid obtained gives \((+)\) Ninhydrin test but not phthalein dye test.
(R)

Reaction with phenyl diazonium salt gives yellow dye.
(S)

Compound will form hydrazone derivative with aldehydic group of glucose.
