Which of the following statement is true?
A. Two diastereomers always have the same melting point.B. A mesocompound and its corresponding racemic mixture always have the same melting point.C. An enantiomer and its corresponding racemic mixture always have the same melting point.D. None of the above.
Homework Answers
C. An enantiomer and its corresponding racemic mixture always have the same melting point.
Reason: and corresponding Islamic mixture always differ in optical activity but remains same with respect to physical and chemical properties.
Diasteriomers can have different melting point.
Meso compound and its corresponding cemach mixture may have different melting point.

Enantiomers have the same physical properties and cannot be separated using typical laboratory methods. In general, separation can be achieved by converting a racemic mixture to two different diastereomers, which can then be separated. Given the racemic amine and chiral resolving agent below, identify the two diastereomers formed. Use the following order X, Y, Z, where X refers to the configuration of the amine, while Y and Z refer to the configuration of the carboxylic acids. The diastereomers can be...
