S lactic acid left and R right are nonsuperposable mirror images of each other In chemistry enantiomer tee from Greek ntios meaning opposite ros part also known as optical isomer archaically termed antipode one two stereoisomers that not identical much hands same except for being reversed along axis cannot made to appear simply by reorientation. Left and right have always had moral connotations the Latin words for these are sinister rectus straight proper. There are few known compounds that do have asymmetric carbon atoms but being nondissymmetric with respect whole molecule not show enantiomerism. The first is known as chiral resolution.

Thus meso tartaric acid has two asymmetric carbon atoms but samples still exhibit optical inactivity because each of the halves molecule is equal and opposite other superposable its geometric mirror image.

Thus the two enantiomers of reactant produce single product. Techniques encompassed include the use of chiral starting materials pool synthesis auxiliaries and catalysts application asymmetric induction
