What are meso compounds with example?

Examples 1 and 2 are classified as meso compounds because they have at least two chiral centers and internal mirror planes, as indicated by the broken lines. In Example 3, hydrogen (H) and chlorine (Cl) are on the internal mirror plane, so Example 3 is still classified as a meso compound.

What compounds are meso?

Meso compounds can exist in many different forms such as pentane, butane, heptane, and even cyclobutane. They do not necessarily have to be two stereocenters, but can have more.

What does it mean when a compound is meso?

Meso compounds are achiral compounds that has multiple chiral centers. It is superimposed on its mirror image and is optically inactive despite its stereocenters.

Are all achiral molecules meso?

All meso compounds are achiral (due to internal compensation as you have mentioned) but all achiral compunds aren’t meso. Look carefully and you’ll be able to spot chiral centres in all the above compounds but you’ll also notice that they have a plane of symmetry (internal compensation) which makes them achiral.

Is tartaric acid a meso?

Meso-tartaric acid is a 2,3-dihydroxybutanedioic acid that has meso configuration.

What’s the difference between achiral and meso?

The key difference between the terms achiral and meso is that achiral compounds have no chiral centers whereas meso compounds have multiple chiral centers. In summary, an achiral compound is the opposite of a chiral compound.

What is meso acid?

Description. Meso-tartaric acid is a 2,3-dihydroxybutanedioic acid that has meso configuration. It is a conjugate acid of a meso-tartrate(1-). ChEBI.

What is the difference between enantiomers and meso compounds?

Meso compounds are molecules having multiple stereocenters, but their mirror images are superimposable. The main difference between meso compound and enantiomers is that meso compounds have an identical mirror image whereas enantiomers have a non-superimposable mirror image.
