Question

For each of the following pairs, indicate if they are (A) the same, (B) constitutional isomers, (C) enantiomers, or (D) diastereomers

The image contains a section of a document showing two structural representations of chemical compounds, likely sugars. Here's the transcription of the chemical structures:

1. Structure (i):
   - A carbon chain with three carbon atoms.
   - The first carbon is bonded to CH2OH and CH3.
   - The second carbon has an OH group and a hydrogen atom.
   - The third carbon has a CHOH group.

2. Structure (iii):
   - A similar carbon chain with three carbon atoms.
   - The first carbon is bonded to CH2OH and CH3.
   - The second carbon has an H atom and an OH group.
   - The third carbon features an additional OH group.

These structures might represent stereoisomers, where the arrangement of atoms differs around the asymmetric carbon, which is significant in organic chemistry for the study of sugars and other similar molecules.

For each of the following pairs, indicate if they are (A) the same, (B) constitutional isomers, (C) enantiomers, or (D) diastereomers.

---

**(i)**

- **Structure 1:** A molecule with OH and CH₃ groups attached.
- **Structure 2:** A molecule with Br and CH₃ groups attached.

**(ii)**

- **Structure 1:** A molecule with Br and CH₃ attached to a central carbon, with two hydrogen atoms.
- **Structure 2:** A molecule with Br, CH₂CH₃, and CH₃ groups attached, with a central carbon bonded to hydrogen.

*Diagrams Explanation:*

The image contains diagrams showing molecular structures with varying substituents. The structures represent different orientations of atoms within the molecules, relevant for determining if they are the same or types of isomers.
