WebA Fischer projection of (2R,3S)−2,3−butanediol is : A B C D Medium Solution Verified by Toppr Correct option is A) 2R, 3S- 2, 3- butanediol ⇒ The compound is optically inactive even though it has 2 chiral carbons because of 2R and 3S. So, the structure should be symmetry in order to be optically inactive. ⇒ They are symmetric.
