WebDec 15, 2024 · The definition of the chirality is the property of any object (molecule) of being non-superimposable on its mirror image. The left and right hand are mirror image to each other, and they are not superimposable, so both left hand and right hand are chiral. WebChiral describes an atom that has four separate groups attached to it, while enantiomers describe the two stereoisomer relations. Enantiomers also have chiral centers in the molecules, but not all molecular stereoisomers are mutually enantiomers. Are enantiomers chemically different?

WebChirality is defined as “an object which is asymmetric and cannot be superimposed over its mirror image is known as chiral or stereocenter”. This property is known as chirality. For example- our hands, legs etc. The object which is symmetric in nature and can be superimposed over its mirror image is known as achiral. For example- cube, cone etc.
