Question

Match the compounds in List-I with the appropriate observations in List-II and choose the correct option List-I List-II --- --- (P) (1) Reaction with phenyl diazonium salt gives yellow dye. (Q) (2) Reaction with ninhydrin gives purple color and it also reacts with FeC l 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 FeC l 3 gives blood red color. (5) After complete hydrolysis, it will give ninhydrin test and it DOES NOT give positive phthalein dye test.
