Verified step by step guidance

Identify the structure of Talose from the provided image. Talose is an aldohexose with the specific configuration of hydroxyl groups as shown in the image.

Compare each of the given structures (i, ii, iii) with the structure of Talose to determine if they are enantiomers, epimers, or neither.

For structure (i), observe the configuration of the hydroxyl groups. Compare it with Talose to see if it is a mirror image (enantiomer) or if only one chiral center differs (epimer).

For structure (ii), perform the same comparison. Check if it is a mirror image of Talose or if it differs at only one chiral center.

For structure (iii), again compare with Talose. Determine if it is a mirror image or if it differs at only one chiral center. Use these observations to label each structure accordingly.
