Question

Match items of Row I with those of Row II

• A. $A \rightarrow$ iii, $B \rightarrow$ iv, $C \rightarrow$ ii, $D \rightarrow$ i
• B. $A \rightarrow iv , B \rightarrow$ iii, $C \rightarrow i , D \rightarrow$ ii
• C. A $\rightarrow$ iii, $B \rightarrow iv , C \rightarrow i , D \rightarrow ii$
• D. A $\rightarrow$ i, B $\rightarrow$ ii, $C \rightarrow$ iii, $D \rightarrow$ iv

Answer 1

The Correct Option is C

The question requires matching structures from Row I with their chemical names in Row II.

To solve this, we need to identify the type of sugar structure in each case:

1. Structure A: This is a glucose structure with an α-anomeric configuration, characteristic of α-D-(−)-Glucopyranose.
2. Structure B: This is a glucose structure with a β-anomeric configuration, characteristic of β-D-(−)-Glucopyranose.
3. Structure C: This is a fructose structure in its furanose form with an α-anomeric configuration, characteristic of α-D-(−)-Fructofuranose.
4. Structure D: This is a fructose structure in its furanose form with a β-anomeric configuration, characteristic of β-D-(−)-Fructofuranose.

Based on this identification, we match:

• A → iii (α-D-(−)-Glucopyranose)
• B → iv (β-D-(−)-Glucopyranose)
• C → i (α-D-(−)-Fructofuranose)
• D → ii (β-D-(−)-Fructofuranose)

The correct answer is: A → iii, B → iv, C → i, D → ii
