In organic chemistry, a molecule is broadly defined as "chiral" if it fundamentally lacks specific e — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

A molecule is chiral strictly if its mirror image is non-superimposable. This occurs if and only if it lacks any Alternating Axis of Symmetry ($S_n$). A Plane of Symmetry ($S_1$) and a Center of Symmetry ($S_2$) are highly common subsets of an $S_n$ axis. However, a molecule can possess a simple rotational axis ($C_n$) and still remain chiral (e.g., standard tartaric acid derivatives possessing a $C_2$ axis).
