Flashcards in Stereochemistry Deck (16)

1
chirality
the ability to exist in two non-superimposable mirror-image forms
2
entaniomers
a pair of non-superimposable mirror-image molc
3
sterioisomers
isomers that have the same connectivity of atoms but different spacial arrangements
4
asymmetric carbons
a carbon that has 4 different groups attached to it
aka chiral carbons
5
chiral center
an atom holding a set of groups in a spacial arrangement that is not superimposable on its own mirror image
6
stereocenter
any atom at which the interchange of two groups gives a stereoisomer
7
the 2^n rule
a molecule with n chiral centers can have a maximum of 2^n stereoisomers
8
absolute configuration
description of the spacial arrangement of the groups attached to a chiral center
9
R/S nomenclature convention
used to assign absolute configuration
uses the Cahn-Ingold-Prelog Priority system to prioritize groups attached to the chiral carbon
10
Optical activity
rotation of the plane of plane-polarized light
11
optically active
a molecule rotates the plane-polarized light
12
dextrorotatory enantiomer
an enantiomer that rotates plane-polarized light clockwise (+)
13
levorotatory enantiomer
an enantiomer that rotates the plan-polarized light counterclockwise (-)
14
Racemic mixture
equal amounts of (+) and (-) enantiomers
15
specific rotation
rotation induced by 1 g/ my of solution
