Define the term "chirality" in organic chemistry.

• A. A property that makes a molecule water-soluble
• B. The ability of a molecule to rotate light
• C. A property of a molecule that makes it non-superimposable on its mirror image, usually due to the presence of a chiral center
• D. A characteristic of molecules that allows them to form isomers

Answer: (C)

Chirality in organic chemistry refers to the concept of a molecule being non-superimposable on its mirror image, which arises when a molecule has a chiral center, typically a carbon atom bonded to four different substituents. This unique configuration results in two distinct stereoisomers, known as enantiomers, that have different spatial arrangements. Since these two forms are mirror images of each other, they cannot be perfectly aligned when placed over one another, which is a fundamental characteristic of chiral molecules. Understanding chirality is crucial because it often plays a significant role in the behavior of molecules in biological systems, influencing how they interact with other chiral molecules in processes such as enzyme activity and drug efficacy. This property is distinct and essential for many organic compounds, particularly in pharmaceuticals where one enantiomer may exhibit desired therapeutic effects while the other could be less effective or cause adverse reactions.
