IsomersCompounds that have identical chemical formulas but
different molecular shapes or structures
Iso-greek “equal or identical”Meros greek “part”
Organic CompoundsMolecules that mainly contain carbon. This
contains substances both naturally found and man made (synthetic).
ButaneC4H10
IsobutaneC4H10
Building Blocks: CarbonIn the organic world, carbon rules. The simplest organic compounds have just carbon and hydrogen. Carbon atom chain together nicely to make whatever length you want from two to two million.
Building Blocks: Hydrocarbons
As the chains get longer, the hydrocarbons go from a gas to a liquid to a more viscous liquid, and finally a solid. The longest chains are polyethylene plastic.
HydrocarbonsThe simplest organic compounds because
they contain only two types of atoms—carbon and hydrogen
Methane CH4
Octane C8H18
Methane, ethane, benzene, octane
Build a model of ButaneC4H10
Build another model of butane with a different structure
Butane Isomer
Other Examples?
IsomersIsomers have the same chemical structure but
different properties because their atoms are arranged differently
The greater the number of atoms in a molecule, the more isomers it is likely to have
