Isomers: Organic Chemistry

isomers

molecule that have the same molecule formula

constitutional isomers

same formula, different connectivity of atoms

stereoisomers

same formula, same connectivity, DIFFERENT spatial arrangement

conformer

rotation of a group around a sigma bond (also known as stereoisomers)

enantiomers

isomers that have the same connectivity

molecules that are mirror images of each other, but are not super imposable

diastereomers

isomers with the same connectivity

molecules who are not mirror images of each other

chiral center or stereocenter

an atom within a molecule that has four DIFFERENT substituents attached to it

chiral

a molecule whose mirror image is not super imposable on itself (has at least one stereocenter)

achiral

a molecule with a plane of symmetry

meso compounds

a molecule whose mirror image is superimposable on itself and must have 2 chiral centers (when comparing molecules, these are the same)
