A chiral molecule is a type of molecule that cannot be superimposed on its mirror image. This means that the molecule and its mirror image are distinct, much like how left and right hands are different. Chiral molecules often contain a carbon atom bonded to four different groups, creating a specific three-dimensional arrangement. Chirality is important in many fields, especially in chemistry and pharmacology. Different chiral forms, known as enantiomers, can have different biological effects. For example, one enantiomer of a drug may be effective, while its mirror image could be harmful or inactive.
