Question

The correct match between item 'I' and item 'II' is

Item I (Compound)	Item II (Reagent)
(1) Lysine	(P) 1-naphthol
(2) Furfural	(Q) ninhydrin
(3) Isopropyl alcohol	(R) $K M n O_{4}$
(4) Vinyl benzene (Styrene)	(S) Ceric ammonium Nitrate

• A. 1-R; 2-P; 3-Q; 4-S
• B. 1-Q; 2-P; 3-R; 4-S
• C. 1-Q; 2-R; 3-S; 4-P
• D. 1- Q; 2-P; 3-S; 4-R

Answer 1

Answer: (D)

Lysine (amino acid) can be tested by ninhydrin as ninhydrin test is used for testing amino acids.

Furfural can be tested by 1-naphthol.

Isopropyl alcohol can be tested by Ceric ammonium nitrate which is a yellow reagent and on reaction with alcohol changes to red.

Vinyl benzene (Styrene) can be tested by $\text{KMn}\text{O}_{4}$ as styrene decolourises alk. $\text{KMn}\text{O}_{4}$ due to presence of unsaturation (double bond).
