Shapes 2 Lecture 2 Flashcards
to change conformation you must
rotate single bond
what must not happen to conformation change
bonds breaking
steroisomers have
different configurations
Compounds with different configurations are called stereoisomers
configurations can be interconverted only by breaking bonds.
what causes barriers to rotation
conjugation between the double bond
equatorial
the periphery of the carbon ring
axial
aligned parallel to the symmetry axis of the ring.
steric strain
Steric strain is the increase in potential energy of a molecule due to repulsion between electrons in atoms that are not directly bonded to each other.
Steric effects are
the effect on molecules of the repulsive force of electrons trying to get as far away from each other as possible.
