Question

For meso tartaric acid, the correct configuration for chiral carbon is

• A. 2R, 3S
• B. 2R, 3R
• C. 2S, 3R
• D. 1D, 2L

Hint:

Meso compounds are optically inactive despite having chiral centers due to internal symmetry that cancels out optical rotation.

Answer 1

The Correct Option is A

Step 1: Understanding Meso Compounds.
Meso compounds have chiral centers but are achiral due to internal symmetry. In meso tartaric acid, the two chiral centers have opposite configurations (R and S). The correct configuration for the chiral carbons in meso tartaric acid is 2R, 3S.
Step 2: Conclusion.
The correct answer is (A), 2R, 3S.
