stereochemistry Flashcards
carbon skeleton
Skeletal
different connectivity of atoms
Constitutional
concerned with the three-dimensional arrangement of atoms and molecules and the effect of this on chemical reactions
Stereochemistry
same connectivity but different spatial orientation of atoms
Stereoisomers
result from restricted rotation around a double bond or on polysubstituted cyclic alkanes
Geometric
different compounds
Configurational
same compound
Conformational
-greek word cheir means hand
-has a nonsuperimposable mirror image
-asymmetrical
Chiral
symmetrical and superimposable mirror image
Achiral
an atom connects to 4 different groups
Stereocenters
- horizontal lines are directed toward the viewer
- vertical lines are directed away from the viewer
Fischer Projection
equimolar misture of 2 enantiomers
Racemic Mixture
stereoisomers that are not mirror images of each other
Diastereomers
