Unit 3 Topic 1b Flashcards
Organic chemistry: Stereochemistry
What are Isomers?
Isomers are molecules with the same molecular formula but different structural formula
What is a Structural isomer?
A structural isomer is an isomer in which the atoms are bonded in a different order in each isomer
What is a Stereoisomer?
A stereoisomer is an isomer in which the order of bonding is the same but the spatial arragments of atoms is different
Stereoisomer 1/2:
What is a Geometric isomer?
A geometric isomer is an isomer that lacks free rotation inside molecules due to a carbon to carbon double bond or a C-C bonded ring structure. It must also have different attached groups to each carbon atom
What are Trans-isomers?
Trans-isomers are isomers where the groups are located on different sides of the bond with restricted rotation
What is a Cis-isomer?
A cis-isomer is an isomer where the groups are located on the same side of the bond with restricted rotation
