4. Consider the species 2,3-butanediol, whose structural formula is: но Он 2,3-butanediol H3C CH3 a) There are three distinct, pure, configurational stereoisomers of 2,3-butanediol, all of which have the same structural formula above. Using any unambiguous notation, draw the three different stereoisomers in the boxes below. (The boxes have been arbitrarily labeled A, B, and C.) A В b) By circling the appropriate terms below, indicate whether each of the three species you drew above is chiral or achiral. A: chiral achiral В: chiral achiral C: chiral achiral c) Two of the above species have the same melting point (19°C). The other species has a different melting point (34°C). Circle the letter of the species which has a melting point of 34°C: A В What characteristic of the other two stereoisomers causes them to share the same melting point (19°C)?
