Stereochemistry Flashcards
These are molecules of different connectivity.
Constitutional Isomers
Compounds with the same molecular formula but different structural formulas.
Constitutional Isomers
CHIRALITY
These have no plane of symmetry and are not identical to their mirror image.
Chiral Molecules
CHIRALITY
These have a plane of symmetry and are identical to their mirror image.
Achiral Molecules
CHIRALITY
TRUE or FALSE: Your hands laid on top of the other are an example of chirality at play.
TRUE
CHIRALITY
The presence of a carbon atom bonded to four different groups represents…?
Chiral Carbon
CHIRALITY
A Chiral Carbon is referred to as the _____ _____.
Chirality Center
CHIRALITY
TRUE or FALSE: The carbon atoms in CH2, CH3, C=O, and C=C can be chirality centers.
FALSE. They cannot.
STEREOCHEMISTRY CONFIGURATIONS
These are molecules that are non-superimposable to their mirror images.
Enantiomers
STEREOCHEMISTRY CONFIGURATIONS
Enantiomers are also called…?
Optical Isomers
CHIRALITY
A set of sequence rules to rank the four groups attached to the chirality center and then looks at the handedness with which those groups are attached.
Cahn-Ingold-Prelog Rules
CAHN-INGOLD-PRELOG RULES
In determining the rank between Cl and O, which would be ranked higher?
Cl, because it has a higher atomic number compared to O.
STEREOCHEMISTRY CONFIGURATIONS
What is the configuration if the curved arrow drawn from 1-4 is clockwise?
R Configuration
STEREOCHEMISTRY CONFIGURATIONS
What is the configuration if the curved arrow drawn from 1-4 is counter-clockwise?
S configuration
STEREOCHEMISTRY CONFIGURATION
These are stereoisomers that are not mirror images.
Diastereomers
