Homework Answers
1. Top left structure: Conformational isomer: amide linkage (NH--CO) is rotated; other than that it is the same molecule.
2. Top right structure: Identical: molecule is flipped and the stereochemistry of all 3 chiral centers changed with it.
3. 1st structure in 2nd row: Structual isomer: Same molecular formula but the different structures.
4: 2nd structure in 2nd row: Diastereomer: Stereochemistry of 1 chiral center (NHCO) is same and the other 2 chiral centers with alcohols are different.
5: Last molecule: Enantiomer: all the chiral centers are opposite.
