Meso-Tartaric acid is optically inactive due to the presence of (a) Molecular symmetry (b) Molecular asymmetry (c) External compensation (d) Two asymmetric carbon atoms. It can be separated into two forms. Optical inactivity of meso -tartaric acid We usually come across in many standard text books of organic chemistry that meso -tartaric acid is optically inactive simply because it has a plane of symmetry [11-13] (point group Cs) and an imaginary mirror plane is drawn across the molecule in … 900+ SHARES. B) Molecular asymmetry . Investigations of isomeric tartaric acid salts, carried out by Louis Pasteur in the mid 19th century, were instrumental in elucidating some of the subtleties of stereochemistry. 1 Structures Expand this section. 900+ VIEWS.
