#### Task:
Label each pair of compounds below as:
a. conformational isomers
b. stereoisomers
c. constitutional isomers
d. identical
#### Compounds:
- **Diagram 1**: A tetrahedral carbon atom with the following substitutions:
- One methyl group (CH₃) on the right.
- One methyl group (CH₃) on the bottom left.
- Three hydrogen atoms (H) on the remaining three positions.
- **Diagram 2**: A tetrahedral carbon atom with the following substitutions:
- One methyl group (CH₃) on the top.
- One methyl group (CH₃) on the bottom right.
- Three hydrogen atoms (H) on the remaining three positions.
#### Possible Answers:
1. conformational isomers
2. stereoisomers
3. constitutional isomers
4. identical
#### Explanation:
**Graphs/Diagrams Description**:
- These diagrams depict the molecular structure of two compounds. Each compound is shown in a tetrahedral configuration, a common shape for compounds with a central carbon atom.
- Both structures have two methyl groups (CH₃) and three hydrogen atoms (H) attached to the central carbon atom. However, their spatial arrangements are different, indicating a different type of isomerism.
#### Concept:
- **Conformational Isomers:** Different spatial orientations of the same molecule that can be converted into one another by rotation around single bonds.
- **Stereoisomers:** Isomers with the same bond structure but differing in the three-dimensional arrangement of atoms.
- **Constitutional Isomers:** Compounds with the same molecular formula but different connectivity of their atoms.
- **Identical:** Molecules that are exactly the same in terms of both connectivity and spatial arrangement.
#### Answer:
These two diagrams represent **conformational isomers**. They exhibit the same connectivity of atoms and overall shape but differ in the spatial orientation of their atoms due to rotation around the single bonds. They can be converted into one another without breaking any bonds, aligning with the definition of conformational isomers.
#### Answer Choices:
- [ ] conformational isomers
- [ ] stereoisomers
- [ ] constitutional isomers
- [ ] identical
