Identify the set of compounds which are enantiomers ?

Options

A.
B.
C.
D.

Explanation

To identify the set of compounds that are enantiomers, we need to understand the concept of enantiomers. Enantiomers are pairs of molecules that are non-superimposable mirror images of each other. This means that if you were to place one molecule in front of a mirror, the reflection would represent the other molecule in the pair.

### Step-by-Step Solution:

1. **Understand the Definition of Enantiomers**:
- Enantiomers are stereoisomers that are mirror images of each other and cannot be superimposed. They typically have at least one chiral center (a carbon atom attached to four different groups).

2. **Examine the Given Options**:
- We have four sets of compounds to analyze. We need to determine which set consists of enantiomers.

3. **Analyze Each Option**:
- **Option 1**: Check if the compounds in this set can be mirror images. Look for the arrangement of groups around the chiral centers.
- **Option 2**: Similarly, analyze the arrangement of groups. If the groups can be rearranged to form a mirror image, they may be enantiomers.
- **Option 3**: Continue the analysis. Check for the presence of chiral centers and whether the configurations can lead to a non-superimposable mirror image.
- **Option 4**: Finally, analyze this set. If the groups are arranged in such a way that they cannot form a mirror image, they are not enantiomers.

4. **Identify the Correct Option**:
- After analyzing all options, identify which set of compounds has the properties of enantiomers (i.e., they are mirror images and non-superimposable).

5. **Conclusion**:
- The correct answer is the option that contains the pair of compounds that are enantiomers.
