Chapter 3 Flashcards
1
Q
conformational isomers
A
compounds with different arrangements that are interconverted by rotating around sigma bonds
2
Q
torsional strain
A
energy increase due to pushing bonds angles smaller or pulling them open wider
3
Q
steric strain
A
energy increase due to atoms bumping into each other
4
Q
torsional angle
A
angle between two substituents you are comparing
5
Q
anti-conformation
A
staggered conformation where the substituents are the maximum angle apart; 180°
6
Q
gauche conformation
A
staggered conformation where substituents are minimum angle apart; 60°
