💡 Solution & Explanation

# Solution **Evaluating Statement-I:** A molecule is chiral if it is **not superimposable on its mirror image**. This is the definition of chirality. Statement-I correctly defines a chiral molecule. $$\boxed{\text{Statement-I is TRUE}}$$ **Evaluating Statement-II:** While most chiral molecules have chiral centers (stereocenters), **not all chiral molecules require them**. Counterexample: **Allenes** and **spiranes** are chiral molecules without chiral centers due to their 3D geometry and restricted rotation. For instance, allene structures have chirality arising from the perpendicular arrangement of substituents on the $sp$ carbons, not from a stereocenter. $$\boxed{\text{Statement-II is FALSE}}$$ **Conclusion on Causal Relationship:** Even if Statement-II were true, it would **not be a correct explanation** for Statement-I. Chirality is fundamentally defined by non-superimposability on the mirror image, not by the presence of chiral centers. The presence of chiral centers is often a *consequence* of chirality, not its cause. $$\boxed{\text{Answer: (C) Statement-1 is True, Statement-2 is False}}$$
