MCAT ORGANIC CHEMISTRY: ISOMERS

Terms in this set (13)

constitutional isomers
same chemical formula different connectivity
physical properties
no change in the composition of matter: melting point, boiling point, etc.
chemical properties
determined by a molecules functional groups
stereoisomers
same chemical formula and connectivity, but different arrangement in 3d space
conformational isomers
differ in their rotation around a single bond
configurational isomers
differ by the breaking of bonds
anti-configuration
largest substituents are 180 degrees are apart
gauche configuration
largest substituents are 60 degrees apart
eclipsed configuration
groups are directly on top of each other
angle strain
results when bond angles deviate from their ideal ones
torsional strain
results when eclipsed and gauche conformations exist
non-bonded strain
arises from groups trying to occupy the same physical space
specific rotation
(+) is clockwise rotation
(-) is counter-clockwise rotation
