- Module 4 - isomerism
- structural isomerism
- compound that have the same molecular formula but a different structural formula
- different branching
- functional groups having different positions on the carbon chain
- the same molecular formulae can give two different functional groups
- compound that have the same molecular formula but a different structural formula
- Stereo-isomerism
- when a compound has the same molecular formula and structural formula but have a different arrangement of atoms in space
- because there this no free rotation about a C = C double bond
- E/Z isomerism
- only occurs in molecules which have a C=C and have two different atoms or groups attached to each carbon Aton either side of the bond
- Cahn-Ingold-Prelong
- different groups are assigned priority based on their atomic number
- higher the atomic number the higher the priority
- different groups are assigned priority based on their atomic number
- cis-trans isomerism
- the same group appears on each side of the molecule
- when a compound has the same molecular formula and structural formula but have a different arrangement of atoms in space
- structural isomerism
