meso-Tartaric acid is optically inactive due to the presence ofa)Molec...
Explanation:
Meso-tartaric acid is a compound with two chiral centers. It has the chemical formula C4H6O6. The two chiral centers are the carbon atoms bonded to the two carboxylic acid groups.
Molecular symmetry:
The molecule of meso-tartaric acid is symmetrical due to the presence of a plane of symmetry. A plane of symmetry divides the molecule into two mirror-image halves that are identical to each other. The plane of symmetry passes through the mid-point of the carbon-carbon double bond.
Due to the presence of molecular symmetry, the molecule of meso-tartaric acid has an internal compensation mechanism that cancels out the optical activity of the two chiral centers. The two mirror-image halves of the molecule cancel out each other's optical rotation, resulting in a net optical rotation of zero.
Therefore, meso-tartaric acid is optically inactive despite having two chiral centers. The presence of molecular symmetry is the reason why meso-tartaric acid is optically inactive.
Conclusion:
Meso-tartaric acid is optically inactive due to the presence of molecular symmetry. The symmetry of the molecule cancels out the optical activity of the two chiral centers, resulting in a net optical rotation of zero.
