Which of the following are resolvable ?

Options

A.
B.
C.
D.

Explanation

To determine which compounds are resolvable, we need to identify if they contain chiral carbon atoms. A chiral carbon atom is one that is attached to four different groups, making the compound optically active and thus resolvable. Let's analyze each option step by step.

### Step-by-Step Solution:

1. **Option A:**
- Draw the structure of the compound.
- Analyze the carbon atoms in the structure.
- Check if any carbon atom is attached to four different groups.
- **Conclusion:** The carbon atom in this compound is not chiral because it does not have four different substituents. Therefore, this compound is non-resolvable.

2. **Option B:**
- Draw the structure of the compound.
- Identify the carbon atom in question.
- Check the groups attached to this carbon atom.
- **Conclusion:** This carbon atom is chiral because it has four different groups attached (e.g., CH3, H, F, and another group). Hence, this compound is optically active and resolvable.

3. **Option C:**
- Draw the structure of the compound.
- Look for any planes of symmetry in the structure.
- **Conclusion:** This compound has a diagonal plane of symmetry, indicating that it is superimposable on its mirror image. Therefore, it is non-resolvable.

4. **Option D:**
- Draw the structure of the compound.
- Identify the carbon atom and the groups attached to it.
- Check if this carbon atom is chiral.
- **Conclusion:** This carbon atom is chiral as it is attached to four different groups (e.g., OH, H, and two other distinct groups). Thus, this compound is optically active and resolvable.

### Final Answer:
The resolvable compounds are **Option B and Option D**.
