Are chair conformations diastereomers?
All these conformations are diastereomeric with the cis conformations. The diequatorial chair conformer of the cis 1,3-dichloro isomer is achiral. It is the major component of a fast equilibrium with the diaxial conformer, which is also achiral. This isomer is also a meso compound.
How do you identify diastereomers?
Among molecules with the same connectivity:
- Molecules that are mirror images but non-superimposable are enantiomers.
- If they aren't superimposable, and they aren't mirror images, then they're diastereomers.

So one has to change one has to stay the same. So let's just keep the OAH the same.
What are diastereomers with examples?
Diastereomers may often include compounds which are ring structures. Imagine, for example, two compounds with a six-membered ring, each with two substituents, a chlorine atom and an ethyl group. They are also not mirror images of each other, just like our previous example, which defines them as diastereomers.
Are diastereomers Nonsuperimposable?
Diastereomers are stereoisomers that are not related as object and mirror image and are not enantiomers. Unlike enatiomers which are mirror images of each other and non-sumperimposable, diastereomers are not mirror images of each other and non-superimposable.
Can chair conformations be Meso?
Which of the given chair conformations represents a meso compound? Explanation: Meso compounds are characterized by an internal plane of symmetry that renders them achiral despite the presence of chiral center(s).
What are the conditions for diastereomers?
Diastereomers 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 (but not all) of the equivalent (related) stereocenters and are not mirror images of each other.
