How to identify meso compounds?
Understand the Problem
The question is asking how to identify meso compounds, which are specific types of molecules that have multiple stereocenters but are superimposable on their mirror images. This involves understanding their structural characteristics and symmetry.
Answer
Look for an internal plane of symmetry and identical substituted stereocenters whose stereochemistry cancels out.
To identify a meso compound, check for an internal plane of symmetry that divides the compound into two mirror-image halves. The molecule must contain two or more identical substituted stereocenters where the stereochemistry of these centers cancels out.

More Information
Meso compounds are achiral despite having multiple stereocenters due to their internal symmetry.
Tips
A common mistake is confusing achiral compounds with meso compounds. Remember, meso compounds must have stereocenters.
