Chiral objects
|
Objects having right- or left-handedness with two different mirror-image forms that are not superimposable.
|
|
|
Achiral objects
|
The opposite of chiral; objects having superimposable mirror images and thus no right- or left-handedness.
|
|
|
Two chiral molecules with the same formula are called
|
enantiomers
|
|
|
Chiral carbon atom
|
A carbon atom bonded to four different groups.
|
|
|
enantiomers (optical isomers)
|
The two mirror-image forms of a chiral molecule.
|
|
|
Stereoisomers
|
Isomers that have the same molecular and structural formulas but different spatial arrangements of their atoms.
|
|
|
A chiral carbon atom aka "chiral center" is a carbon atom bonded to:
|
a chiral carbon atom bonded to four different groups.
|
|
|
The presence of one chiral carbon atom always produces:
|
a chiral molecule that exists in two mirror-image forms.
|
|
|
If a molecule has two or more chiral carbon atoms, is it chiral?
|
It may or may not be, depending on its overall shape.
|
|
|
The two mirror-image forms of a chiral molecule like alanine are called:
|
either enantiomers or optical isomers
|
|
|
How do pairs of enantiomers often differ?
|
enantiomers often differ in their biological activity, odors, tastes, or activity as drugs.
|
|
|
Two examples of the differences between enantiomers are found in:
|
the differences in taste between L-carvone in spearmint and D-carvone in caraway.
