Isomerism
Isomers - different compounds having the same molecular formula but different structural
formulas
There are two type of Isomers:
Constitutional isomerism: Different connections among atoms in the
• Skeleton
• Position
• Functional group
Stereoisomerism: Same
connectivity among
atoms, but these
atoms differ in spatial orientation
• geometric
• conformational
• optical
