Question

Match the types of terpenes under column I with their respective examples under Column II

Column I Types of terpenes		Column II  Examples
A	Monoterpenes	I	Lycopene
B	Diterpenes	II	Camphor
C	Sesquiterpenes	III	Taxol
D	Tetraterpenes	IV	Zingiberene

Choose the correct answer from the options given below :

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

Answer 1

The Correct Option is B

To solve this matching problem, we need to associate the types of terpenes with their respective examples. Let's evaluate each option independently based on our understanding of terpenes:

1. Monoterpenes: These are terpenes that consist of two isoprene units and generally have the molecular formula C₁₀H₁₆. Common examples include Limonene, Myrcene, and Camphor. Therefore, the correct match for Monoterpenes is Camphor (II).
2. Diterpenes: Diterpenes are composed of four isoprene units and have the molecular formula C₂₀H₃₂. Examples include Retinol, Phytol, and Taxol. Thus, for Diterpenes, the correct match is Taxol (III).
3. Sesquiterpenes: These contain three isoprene units with the formula C₁₅H₂₄. Zingiberene, which is found in ginger, is an example. Hence, the match for Sesquiterpenes is Zingiberene (IV).
4. Tetraterpenes: They are composed of eight isoprene units, resulting in a structure like that of Lycopene. Tetraterpenes often include carotenoids like Lycopene. Therefore, the match for Tetraterpenes is Lycopene (I).

Based on this analysis, the correct matching is:

• A - II (Monoterpenes - Camphor)
• B - III (Diterpenes - Taxol)
• C - IV (Sesquiterpenes - Zingiberene)
• D - I (Tetraterpenes - Lycopene)

Hence, the correct answer is (A)-(II), (B)-(III), (C)-(IV), (D)-(I).
