### Topic: Formation of FuranosesThis educational content focuses on the ability of certain sugars to form furanoses without undergoing isomerization to a different sugar. The image depicts five different sugar molecules, each represented by their structural formulas:1. **Molecule 1**: Features a chain of carbon atoms with hydroxyl (OH) groups attached.2. **Molecule 2**: Similar structure with variations in the placement of hydroxyl groups.3. **Molecule 3**: Presents another variation in hydroxyl group structure.4. **Molecule 4**: Displays a unique arrangement compared to the first three.5. **Molecule 5**: Contains arrangements mirroring some of the previous molecules' features.Each molecule is labeled with a number from 1 to 5, indicating different structural configurations ranging from aldoses to ketoses.#### QuestionWhich of the sugars can form furanoses without undergoing isomerization to a different sugar?#### Options- a. 1- b. 2- c. 4- d. 5- e. 3Students should analyze the structural differences to determine which molecules can directly cyclize to form furanoses. Understanding the position of functional groups, particularly the hydroxyl and carbonyl groups, is crucial for identifying potential cyclization pathways.

Five membered cyclic hemiacetal is called furanose. It is four carbon atoms and one oxygen atoms…
