Question

Which of the following compound(s) is/are chiral?

• A. Only A and B
• B. Only B
• C. Only B and C
• D. Only A

Hint:

A chiral compound has no plane of symmetry and cannot be superimposed on its mirror image.

Answer 1

The Correct Option is A

Step 1: Chiral Molecule 
A molecule is chiral if it has no plane of symmetry and if it has a non-superimposable mirror image (i.e., it can have an enantiomer). 
Step 2: Explanation of the Compounds 
Compound A: This molecule has a chiral center due to the different substituents attached to the central carbon, making it chiral.
Compound B: It also has a chiral center and is chiral because the structure does not have a plane of symmetry.
Compound C: While the molecule might have substituents, the symmetry of the structure (if it has a plane of symmetry) can make it achiral. 
Step 3: Conclusion 
Thus, compounds A and B are chiral, and C is not.
