WebIn undergraduate organic chemistry, most chiral molecules exhibit point chirality- they have at least one sterocenter and don't have a plane of symmetry. Molecules a) and b) both have stereocenters, but they also both have planes of symmetry, so neither is chiral (they are both meso compounds). Molecule can also be chiral about an axis.

When my textbook is discussing stereoisomers with more than one chiral centers, it's using notation like (2 S ,3 S) being an enantiomer with (2 R ,3 R) and so forth. I understand R and S configuration, and I'm guessing there are two items in each brackets to represent the two chiral centers (so 2 S, 3 S would at least mean that both chiral ...

WebCHIRALITY. Because of the tetrahedral geometry of saturated carbon and the associated three-dimensional properties, molecules can have chirality as one stereochemical feature. Any object is chiral if it is different (nonsuperimposable) than its mirror image. Likewise a molecule is chiral if it is nonsuperimposable on its mir-ror image. Webchi·ral·i·ty. (kī-răl′ĭ-tē) n.
