CHEM 210 Study Guide - Midterm Guide: Ethanol, Chemical Formula, Stereoisomerism
Document Summary
Different molecular that shares the same molecular formula but differs in their connectivity/ skeleton. Same molecule with the same formula and connectivity/skeleton but with different rotations around single sigma bonds. Different molecules with same formula and connectivity/skeleton but different in their 3d orientation of attachment. The location along a connectivity/skeleton where differences in the 3d orientation of attachment result in different molecules (stereoisomers) May or may not be a chiral center. Chiral center = chiral carbon = chiral stereocenter. An sp3 tetrahedral carbon bound to four chemically distinct groups. Will exhibit r (movement to the right) or s (movement to the left) absolute stereocon guration. E (opposite side) or z (same side) con guration. Cis (atoms locked on same side of a bond) or trans (atoms locked on opposite side of a bond) con ruation. 50/50 racemic mix of enantiomers is optically inactive (they cancel each other out) 50/50 racemic mix of enantiomers is optically inactive.
