Chapter 4: 4.3 Stereoisomers I - Conformational Isomers Flashcards
1
Q
Define:
Conformational Isomers
A
Have the same molecular formula and bond connectivity but are isomers by bond rotation
2
Q
What are the most common examples of conformational isomers in organic chemistry?
A
Alkanes
3
Q
How are conformational isomers usually shown?
A
Using Newman projections or Fisher projections
4
Q
True or False:
Conformational isomers are present when there is a pi bond
A
False, they are never present when there is a pi bond (conformational isomers are just the same molecule with the rotation around a single bond)
5
Q
Why are different conformers favoured?
A
Enthalpic reasons
6
Q
What types of conformations are there?
A
- Staggered (anti or gauche)
- Eclipsed
