An enantiomer is a molecule that is a mirror image of another molecule but cannot be superimposed onto it. To determine if a molecule is an enantiomer, we need to compare its spatial arrangement of atoms with its mirror image. If the two molecules are non-superimposable mirror images of each other, then they are enantiomers. **

Chirality refers to the property of a molecule that cannot be superimposed on its mirror image. Enantiomers are a pair of molecules that are non-superimposable mirror images of each other. An asymmetric carbon atom, also known as a chiral carbon, is a carbon atom that is bonded to four different groups, leading to the molecule having chirality. This asymmetry results in the molecule having two enantiomers, which have different chemical and biological properties. **

The enantiomer of menthol is neomenthol. Neomenthol is the mirror image of menthol, meaning that their molecular structures are non-superimposable. The diastereomer of L-isoleucine is D-allo-isoleucine. Diastereomers are stereoisomers that are not mirror images of each other. D-allo-isoleucine has a different spatial arrangement of atoms compared to L-isoleucine, resulting in different physical and chemical properties. **
