Q13 / 14 · NTA Abhyas (JEE Main) 2020 · Chemistry · Practical Chemistry

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) KMnO4
(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
  • Correct answer
    D
    1- Q; 2-P; 3-S; 4-R

Solution

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 KMnO4 as styrene decolourises alk. KMnO4 due to presence of unsaturation (double bond).

Hence, the correct answer is option: 'D'.
