Ques. 1JEE Main 2024, 1 February (Evening Shift)

Match List - I with List - II. Choose the correct answer from the options given below :

  1. (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
  2. (A)-(III), (B)-(I), (C)-(II), (D)-(IV)
  3. (A)-(IV), (B)-(II), (C)-(I), (D)-(III)
  4. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Answer

(2) (A)-(III), (B)-(I), (C)-(II), (D)-(IV)

Solution

(A): Zn dust removes –OH: C6H5OH + Zn C6H6 + ZnO ⇒ (A) is (III)

(B): Reimer–Tiemann reaction ⇒ –CHO enters ortho ⇒ salicylaldehyde ⇒ (B) is (I)

(C): Kolbe's reaction ⇒ –COOH enters ortho ⇒ salicylic acid ⇒ (C) is (II)

(D): conc. HNO3 ⇒ 2,4,6-trinitrophenol ⇒ picric acid ⇒ (D) is (IV)

∴ (A)-(III), (B)-(I), (C)-(II), (D)-(IV)

Answer: (2)
