Chapter 3.2: Stereoisomerism Flashcards
Define diastereomers
stereoisomers that are not mirror images of each other; refers to relationships among two or more objects
What are stereoisomers that are not mirror images of each other; refers to relationships among two or more objects?
diastereomers
Define stereocenter
an atom, most commonly carbon, about which exchange of two groups produces a stereoisomer
What are enantiomers that lack a chiral center and differ because of hindered rotation?
atropisomers
What is an atom, most commonly carbon, about which exchange of two groups produces a stereoisomer?
stereocenter
What are isomers that have the same molecular formula and the same connectivity of their atoms but a different orientation of their atoms in space?
stereoisomers
Define enantiomers
stereoisomers that are nonsuperposable mirror images of each other; refers to the arrangement of atoms about a stereocenter

enantiomers
Define atropisomers
enantiomers that lack a chiral center and differ because of hindered rotation
Define stereoisomers
isomers that have the same molecular formula and the same connectivity of their atoms but a different orientation of their atoms in space
What are isomers that differ by the configuration of substituents on an atom. Refers to the arrangement of atoms about a stereocenter?
configurational isomers
Define chiral center
a tetrahedral atom, most commonly carbon, that is bonded to four different groups; also called a chirality center
