Which of the following compounds can have superimposable mirror image?

Options

A.
B.
C.
D.

Explanation

To determine which of the given compounds can have a superimposable mirror image, we need to analyze each compound for the presence of a plane of symmetry. A compound with a plane of symmetry will have a mirror image that can be superimposed onto the original compound.

### Step-by-Step Solution:

1. **Understanding Superimposable Mirror Images**:
- A superimposable mirror image means that when you place the mirror image on top of the original compound, they match perfectly. This typically occurs when there is a plane of symmetry in the molecule.

2. **Identifying the Compounds**:
- Let's denote the compounds as A, B, C, and D for simplicity. We will analyze each compound for symmetry.

3. **Analyzing Compound A**:
- Check if a plane of symmetry can be drawn through the compound.
- If a plane of symmetry can be drawn that divides the compound into two equal halves, then it can have a superimposable mirror image.
- **Conclusion for A**: Yes, it has a plane of symmetry and thus has a superimposable mirror image.

4. **Analyzing Compound B**:
- Repeat the process for compound B.
- Look for any symmetry that divides the compound into two equal halves.
- **Conclusion for B**: Yes, it has a plane of symmetry and thus has a superimposable mirror image.

5. **Analyzing Compound C**:
- Check for symmetry in compound C.
- If you can find a plane of symmetry, it will indicate a superimposable mirror image.
- **Conclusion for C**: Yes, it has a plane of symmetry and thus has a superimposable mirror image.

6. **Analyzing Compound D**:
- Finally, check compound D for any symmetry.
- If the positions of the substituents (like OH groups) are different on either side of a potential plane of symmetry, then it does not have a superimposable mirror image.
- **Conclusion for D**: No, it does not have a plane of symmetry and thus does not have a superimposable mirror image.

7. **Final Answer**:
- Compounds A, B, and C can have superimposable mirror images, while compound D cannot.
