Optically Active Isomers of Tartaric Acid
Tartaric acid has two chiral centers, which means it can exist in multiple stereoisomeric forms, some of which are optically active.
Types of Isomers
- Mesotartaric Acid: This is an achiral compound despite having two chiral centers. It is optically inactive due to internal compensation.
- D-tartaric acid: This enantiomer rotates plane-polarized light in one direction.
- L-tartaric acid: This enantiomer rotates plane-polarized light in the opposite direction.
Number of Optically Active Isomers
- There are two optically active isomers of tartaric acid: D-tartaric acid and L-tartaric acid.
- These two enantiomers are non-superimposable mirror images of each other, making them optically active.
- Since mesotartaric acid is optically inactive, it does not contribute to the total count of optically active isomers.
Therefore, the correct answer is option B, which is 2.
