Isomers

Molecules with same molecular formula but different structure or arrangement. Divided into constitutional and stereoisomers.

New cards

Constitutional Isomers

➤Different bonding patterns
➤ Atoms can physically move and arrange bonds differently

New cards

Plane of Symmetry

A dividing plane that splits a molecule into two identical halves

8
New cards

Meso Compounds

Achiral molecule with chirality centers that is identical to its mirror image
