## Question 9

### Structure A
![Structure A](image_url)
- Carbon (C) is bonded to four different groups: a bromine (Br), an ethyl group (CH₂CH₃), a methyl group (CH₃), and a hydrogen (H).

### Structure B
![Structure B](image_url)
- Carbon (C) is bonded to four different groups: a bromine (Br), an ethyl group (CH₂CH₃), a methyl group (CH₃), and a hydrogen (H).

**Determine the relationship between the structures above. Are they the same molecule, constitutional isomers, or stereoisomers? If A and B are stereoisomers, further classify them as diastereomers or enantiomers.**

- ○ A and B are the same molecule
- ○ A and B are constitutional isomers
- ○ A and B are stereoisomers and diastereomers
- ○ A and B are stereoisomers and enantiomers

**Explanation of terms:**
- **Same molecule:** If the two structures represent the exact same molecule in 3D space.
- **Constitutional isomers:** Molecules with the same molecular formula but different connectivity of atoms.
- **Stereoisomers:** Molecules with the same molecular formula and connectivity, but different spatial arrangements of atoms.
  - **Diastereomers:** Stereoisomers that are not mirror images of each other.
  - **Enantiomers:** Stereoisomers that are non-superimposable mirror images of each other.
