Enantiomers are stereoisomers which are non-superimposable mirror images Remember: A molecule is chiral if it is not superimposable on its mirror image.

are stereoisomers that are not mirror images. Answer: d 4. is an atom in a molecule that is bonded to four different atoms or groups of atoms. Answer: b 5. are molecules which contain chirality centers and a plane of symmetry. Answer: f Assertion: Stereoisomers which are not mirror image of each other are called diastereomers.
Typically, you can only have diastereomers when the molecule has two or more chiral Mirror images that can be superposed are achiral (not chiral). 5. Chapter 5. © 2013 Pearson Education, Inc. Stereoisomers. Enantiomers: Compounds that are A pair of stereoisomers that are not mirror images of one another.

Diastereomers (sometimes called diastereoisomers) are a type of a stereoisomer. Diastereomerism occurs when two or more stereoisomers of a compound have different configurations at one or more (but not all) of the equivalent (related) stereocenters and are not mirror images of each other.
But a diastereomer is any stereoisomer that is not an enantiomer. The cis and trans isomers of but-2-ene are isomers that are not mirror images of each other, so they are diastereomers.
This stereoisomer, which is a sugar called D-threose, is not a mirror image of erythrose. D-threose is a diastereomer of both D-erythrose and L-erythrose. The definition of diastereomers is simple: if two molecules are stereoisomers (same molecular formula, same connectivity, different arrangement of atoms in space) but are not enantiomers, then they are diastereomers by default.
They are usually described as having diastereomers-stereoisomers that are not enantiomers, that is, not mirror images of each image; an achiral molecule is superimposable on its mirror image. A stereoisomer is chiral if its mirror image is not identical or superimposable on the original molecule. It is achiral if the molecule and its mirror image are Diastereomers – Any pairing of stereoisomers that are NOT mirror images of each other.

When two diastereoisomers differ from each other at only one stereocenter they are epimers. Each stereocenter gives rise to two different configurations and thus typically increases the
