Optically active compounds having no chiral carbon. It is optically inactive due … Meso-tartaric acid is a 2,3-dihydroxybutanedioic acid that has meso configuration. Its angle of optical rotation is also 0°. ... A meso compound is optically inactive due to internal compensation. 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 … C) External compensation . Correct Answer: A. III is meso-form of tartaric acid.
