1
Q

A
Share the same molecular formula but have the atomic bonds at different places
(will have different names eg: 1,1-dimethylcyclohexane vs 1,4-dimethylcyclohexane)
2
Q
What is a stereoisomer?
A
Compounds with the same molecular formula, same order of connection (base name) but connection of atoms that differ in 3D geometry
3
Q
What are the two types of stereoisomers?
A
- Diastereomers
2. Enantiomers
4
Q
What is a diastereomere?
A
Stereoisomers that are not mirror images
5
Q
What is an enantiomer?
A
Stereoisomers that are non-superposable mirror images of each other
6
Q
What does cis mean in terms of stereoisomers?
A
the substituents are on the same side of the ring
7
Q
What are trans stereoisomers?
A
Have the substituents on opposite sides of the ring
