STEREOCHEMISTRY 1 (STUDY NOTES)
What are enantiomers? <<answer>>They are stereoisomers that are non-superimposable mirror images
of each other
In order for this to be the case, they must contain a chiral centre (stereocenter)
What are isomers?<<answer>>Two or more compounds having the SAME MOLECULAR FORMULA but
different structural formula and properties.
Explain the difference between structural isomers and stereoisomers<<answer>>-structural isomers
have the same molecular formula but differ in the order in which atoms are bonded together
-stereoisomers have the same molecular formula and order in bonding of constituent atoms, but differ in
the 3D arrangement in space
Are enantiomers stereoisomers?<<answer>>Yes
What are diastereomers?<<answer>>stereoisomers that are not mirror images
They differ in the absolute configuration of one or more of their stereocenters, that's why they're not
mirror images of each other
How are enantiomers usually classified?<<answer>>By optical activity: in terms of the direction in which
they rotate polarized light
- (+) d (dexter) dextrorotatory
