Answer:
Meso Compound:
An optically inactive compound whose molecule is superimposable on its mirror image in spite of the presence of chiral carbon atoms is called a meso compound.
Example: In Tartaric acid
The molecule contains two chiral carbon and the number of optical isomers should be 2n =22 = 4 but number of optical isomer is reduced to 3 because one molecule has a plane of symmetry.The stereoisomers of tartaric acid are,
I and II are enantiomers (non-super imposable).
III and IV are meso form (super imposable).
