Which one of the following compounds will show enantiomerism ?

Options

A.
B.
C.
D.

Answer

To determine which compound shows enantiomerism, we need to identify if any of the given compounds are chiral. A chiral molecule is one that cannot be superimposed on its mirror image and typically has a carbon atom bonded to four different groups.

### Step-by-Step Solution:

1. **Understand Enantiomerism**: Enantiomers are pairs of molecules that are non-superimposable mirror images of each other. For a compound to exhibit enantiomerism, it must be chiral.

2. **Identify Chiral Centers**: A chiral center is usually a carbon atom that is bonded to four different substituents. This creates a situation where the molecule has a distinct left-handed and right-handed form.

3. **Examine the Given Compounds**: Look at each of the provided compounds and identify if there is a carbon atom bonded to four different groups.

4. **Analyze Each Option**:
- **Option A**: Check if there is a chiral carbon. If all substituents are not different, it cannot show enantiomerism.
- **Option B**: Similarly, analyze this compound for a chiral center.
- **Option C**: If this compound has a carbon atom bonded to four different groups, it is chiral and will show enantiomerism.
- **Option D**: Check this compound for chiral centers as well.

5. **Conclusion**: After analyzing all options, the compound that has a chiral carbon (four different groups attached) will be the one that shows enantiomerism.

6. **Final Answer**: Based on the analysis, the correct option is **C**, as it contains a chiral carbon atom.
