Question

A Fischer projection of (2R, 3S)-2,3-butanediol is:

• A. A
• B. B
• C. C
• D. D

Hint:

The Fischer projection shows the 3D arrangement of atoms in a molecule, with horizontal bonds coming out of the plane and vertical bonds going behind.

Answer 1

The Correct Option is A

The Fischer projection for (2R, 3S)-2,3-butanediol should correctly show the stereochemistry at both the 2nd and 3rd positions as given by the R and S configurations.
Final Answer: \[ \boxed{HO - CH_2 - CH_2 - OH} \]
