Question

consider the molecules (a - e) drawn below: which structure(s) is/are a diastereomer of structure c? structure a structure b structure d structure e none of the structures are a diastereomer of structure c. question 14 (10 points) saved

Explanation:

Step1: Recall diastereomer definition

Diastereomers are stereoisomers that are not enantiomers. They have different physical properties.

Step2: Analyze each structure with respect to C

For structure A: Compare the configurations of chiral - centers. It has different configurations at some chiral - centers compared to C and is not an enantiomer, so it is a diastereomer.
For structure B: Compare the configurations of chiral - centers. It is an enantiomer of A and has a different relationship with C. By comparing the configurations of all chiral - centers, it is a diastereomer of C.
For structure D: Compare the configurations of chiral - centers. It has a different configuration at some chiral - centers compared to C and is not an enantiomer, so it is a diastereomer.
For structure E: Compare the configurations of chiral - centers. It has a different configuration at some chiral - centers compared to C and is not an enantiomer, so it is a diastereomer.

Answer:

A. structure A
B. structure B
C. structure D
D. structure E
