Conformers and Geometric Isomers
Cards in this deck (7)
- 1ConformationsDifferent arrangements of atoms that result from the rotation about C-C single bond.
- 2Geometric isomershave the same molecular formula and the same connectivity of atoms.
differ in the arrangement of the atoms in space. - 3Geometric isomerism of Alkenestwo identical groups on the same side of the double bond -> cis
two identical groups on the opposite sides of the double bond --> trans - 4E or Z designation for alkenesused to assign priorities to the substituent groups on the double bond carbons.
if higher priorities on the same side of the double bond, the alkene is designated Z. if on the opposite side, the alkene is designated E.
- 5Cahn-Ingold-Prelog Sequence rule 1consider each double bond seperated.
rank the 2 atoms directly attached toeach carbon according to atomic number.
higher atomic number higher priority.
- 6Cahn-Ingold-Prelog Sequence rule 2if a decision can't be made by ranking the first attached atom in the substituent, look at subsequent atoms until the fisrt difference is found.
- 7Cahn-Ingold-Prelog Sequence rule 3multiple bonded atoms are considered to be equivalent to the same number of single bonded atoms.
