Question

Match the following common names in List-I with IUPAC names given in List-II.

List-I: (A) Acrolein (B) Phthaldehyde (C) Crotonaldehyde (D) Cinnamaldehyde

List-II: (I) But-2-enal (II) 3-Phenylprop-2-enal (III) Prop-2-enal (IV) Benzene-1, 2-dicarbaldehyde

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

Answer 1

Answer: (A)

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

Answer 2

1. Acrolein: $\text{CH}_2=\text{CH-CHO}$ is Prop-2-enal.
2. Phthaldehyde: Benzene-1,2-dicarbaldehyde.
3. Crotonaldehyde: $\text{CH}_3\text{-CH=CH-CHO}$ is But-2-enal.
4. Cinnamaldehyde: $\text{C}_6\text{H}_5\text{-CH=CH-CHO}$ is 3-Phenylprop-2-enal. Therefore, the matching is (A)-(III), (B)-(IV), (C)-(I), (D)-(II).
