M3: L-4 Flashcards
1
Q
What are constitutional isomers?
A
Isomers with a different order of attachment of their atoms
2
Q
What are stereoisomers?
A
Isomers with the same order of attachment of atoms, but a different orientation of their atoms in space
3
Q
What are enantiomers?
A
Stereoisomers that are non-super impossible mirror images of each other
4
Q
What are Diastereomers?
A
Stereoisomers that are not mirror images of each other
5

6

A
Cis
7
Q
What is the sequence rules of preferred atoms or groups to determine polarity (Z or E) of an atom?
A
- priorities assigned to groups based on atomic number
- where two atoms are the same, consider what is attached to each of them
- one atom or a higher atomic number takes precedence over several of a lower atomic number
- two atoms of a particular atomic number take precedence over one atom of the same atomic number
- double bonds are treated as two single bonds
