QUESTION:
Think about the helical coil of a telephone cord or a spiral binding. Suppose that you viewthe spiral from one end and find that it is a left-handed twist. If you view the same spiralfrom the other end, is it a right-handed or left-handed twist?
ANSWER:Chirality
Chirality is a property of a molecule or ion that is non-superimposable on its mirror image. In other words, it is a molecule or ion that cannot be superimposed on its own mirror image.
Chirality is a result of the presence of a chiral center, which is an atom that is bonded to four different groups of atoms or ligands. Chiral molecules can exist in two different forms, known as enantiomers, which are mirror images of each other but are not superimposable. These enantiomers are also known as optical isomers and they can rotate the plane of polarized light in opposite directions.
Chirality is a fundamental concept in chemistry, particularly in organic and biomolecular chemistry, and plays an important role in the properties and biological activity of molecules.
