What does meso mean in organic chemistry ?

Answer 1

Meso means that a molecule has an internal plane of symmetry.

The word meso comes from Greek meso = middle.

In Organic Chemistry, a meso compound is a compound with two or more stereocentres that has an internal plane of symmetry.

This internal plane cuts the molecule into two halves, each of which is a mirror image of the other.

Here is an example of a meso compound with its internal mirror plane.

Answer 2

In organic chemistry, "meso" refers to a molecule that contains chiral centers but is achiral as a whole due to internal symmetry. This means that while individual parts of the molecule are chiral and could potentially exist in two mirror-image forms (enantiomers), the overall molecule is symmetrical and does not have distinct mirror-image forms.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
