Question

Among the following four structures I to IV, it is true that

• A. only I and II are chiral compounds.
• B. only III and IV are chiral compounds.
• C. all four are chiral compounds.
• D. only I is a chiral compound.

Hint:

A chiral molecule lacks a plane of symmetry and has a non-superimposable mirror image (enantiomer).

Answer 1

The Correct Option is A

Step 1: Understand chirality.
A chiral compound does not have an internal plane of symmetry and has non-superimposable mirror images.
Step 2: Conclusion.
Only structures I and II are chiral compounds. Final Answer: \[ \boxed{\text{Only I and II are chiral compounds.}} \]
