💡 Solution & Explanation

# Analysis of Chirality Statements **Evaluate Statement-1:** "Molecules that are not superimposable on their mirror images are chiral" ✓ **TRUE** — This is the fundamental definition of chirality. Non-superimposability with mirror image = chiral molecule. --- **Evaluate Statement-2:** "All chiral molecules have chiral centres" ✗ **FALSE** — Counterexample exists: **Allenes** and **biphenyls** with bulky ortho-substitutents exhibit chirality WITHOUT possessing a chiral center (asymmetric carbon). Their chirality arises from: - Axial chirality (allenes) - Restricted rotation around C-C bonds (hindered biphenyls) --- **Why is Statement-2 NOT a correct explanation for Statement-1?** Even though Statement-2 were true, it would be unnecessarily restrictive. Statement-1 correctly identifies chirality by the mirror-image test (which applies universally), while Statement-2 would limit chirality only to molecules with chiral centers. --- **Answer: (C)** — Statement-1 is True, Statement-2 is False
