JEE MAIN - Chemistry (2025 - 28th January Evening Shift - No. 6)
Match List-I with List-II.
List - I (Saccharides) | List - II (Glycosidic-linkages found) |
---|---|
(A) Sucrose | (I) α 1 $-$ 4 |
(B) Maltose | (II) α 1 $-$ 4 and α 1 $-$ 6 |
(C) Lactose | (III) α 1 $-$ β 2 |
(D) Amylopectin | (IV) β 1 $-$ 4 |
Choose the correct answer from the options given below :
(A)-(III), (B)-(I), (C)-(IV), (D)-(II)
(A)-(I), (B)-(II), (C)-(III), (D)-(IV)
(A)-(II), (B)-(IV), (C)-(III), (D)-(I)
(A)-(IV), (B)-(II), (C)-(I), (D)-(III)
Explanation
(A) Sucrose $\rightarrow \alpha_1-\beta_2$ Glycosidic linkage
(B) Maltose $\rightarrow \alpha$ 1-4 Glycosidic linkage
(C) Lactose $\rightarrow \beta$ 1-4 Glycosidic linkage
(D) Amylopectin $\rightarrow \alpha$ 1-4 and $\alpha$ 1-6 Glycosidic linkage
$$\mathrm{A}-\mathrm{III}, \mathrm{~B}-\mathrm{I}, \mathrm{C}-\mathrm{IV}, \mathrm{D}-\mathrm{II}$$
