The correct match between item I and item II is Item I (Compound)...

The correct match between item II and item IIII is
Item II (Compound) Item IIII (Reagent)
a.a . Lysine p.p . 1−1 -naphthol
b.b . Furfural q.q . Ninhydrin
c.c . Benzyl alcohol r.r . KMnO4{KMnO}_{4}
d.d . Styrene s.s . Ceric ammonium nitrate
The correct match between item I and item II is Item I (Compound) Item II (Reagent) a . Lysine p . 1 - naphthol b .

Options

  1. Aa→q,b→r,c→s,d→pa \to q, b \to r, c \to s, d \to p
  2. Ba→q,b→p,c→s,d→ra \to q, b \to p, c \to s, d \to r
  3. Ca→r,b→p,c→q,d→sa \to r, b \to p, c \to q, d \to s
  4. Da→q,b→p,c→r,d→sa \to q, b \to p, c \to r, d \to s

Correct answer

B. a→q,b→p,c→s,d→ra \to q, b \to p, c \to s, d \to r

Step-by-step solution

Lysine→\toNinhydrin (this is given out by all the amino acids and Lysine is an amino acid.)

Furfural→\to1−1 -naphthol.

Rapid furfural test is used to distinguish between glucose and fructose. In this test, the sugar solution is added to 1−1 -naphthol and concentrated HClHCl.

Benzyl alcohol → ceric ammonium nitrate.

Ceric ammonium nitrate test is used for testing of alcohols.

The correct match between item I and item II is Item I (Compound) Item II (Reagent) a . Lysine p . 1 - naphthol b .

Styrene undergoes oxidation when treated with KMnO4{KMnO}_{4}.
