each of a pair of molecules that are mirror images of each other.called enantimers
ex examples · Enantiomer. (S)-(+)-lactic acid (left) and (R)-(–)-lactic acid (right) are nonsuperposable mirror images of each other.
Diastereomers are a type of a stereoisomer. Diasteoreomers are defined as non-mirror image non-identical stereoisomers. Hence, they occur when two or more stereoisomers of a compound have different configurations at one or more of the equivalent stereocenters and are not mirror images of each other.
simple carbon atom that has a hydrogen, fluorine, bromine, and hydroxyl (-OH) groups bonded to it. This carbon would be classified as a stereocenter since it indeed has four different groups bonded to it.
An asymmetric carbon atom is bonded to four different substituents

meso compound or meso isomer is a non-optically active member of a set of stereoisomers, at least two of which are optically active. This means that despite containing two or more stereogenic centers, the molecule is not chiral. A meso compound is "superposable" on its mirror image.
