Question

Match List-I with List-II. 

List-I (Systematic Name)	List-II (Common Name)
(A) Dodecanoic	(I) Arachidonic
(B) cis-9-Octadecenoic	(II) Lauric
(C) cis-5, cis-8, cis-11, cis-14, cis-17 Eicosapentaenoic	(III) Oleic
(D) cis-5, cis-8, cis-11, cis-14 Eicosatetraenoic	(IV) EPA

Choose the correct answer from the options given below.

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

Hint:

Remember prefix numerical roots:
- "Dodeca" refers to 12 carbons (Lauric acid).
- "Eicosa" refers to 20 carbons (EPA and Arachidonic acid).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Fatty acids are classified and named using both systematic IUPAC nomenclature (describing chain length and unsaturation) and common historical names.

Step 2: Detailed Explanation:
- (A) Dodecanoic acid: A 12-carbon saturated fatty acid (12:0). Its common name is Lauric acid (II).
- (B) cis-9-Octadecenoic acid: An 18-carbon monounsaturated fatty acid (18:1). Its common name is Oleic acid (III).
- (C) cis-5, cis-8, cis-11, cis-14, cis-17 Eicosapentaenoic acid: A 20-carbon polyunsaturated fatty acid with 5 double bonds (20:5). Its common name is Eicosapentaenoic acid or EPA (IV).
- (D) cis-5, cis-8, cis-11, cis-14 Eicosatetraenoic acid: A 20-carbon polyunsaturated fatty acid with 4 double bonds (20:4). Its common name is Arachidonic acid (I).

Step 3: Final Answer:
Matching the pairs gives (A)-(II), (B)-(III), (C)-(IV), (D)-(I), which corresponds to Option (C).
