- Isomers
- >Same molecular formulas but different structural formula
- 3 different structural formulas
- Chain isomer- different arrangement of the c skeletal, some straight and others branched
- Positional isomers- same everything bar where the atom or group of atoms is attached
- Functional group- same atoms arranged in different functional groups
- Steroisomers
- >Same structural formula but different arrangement in space
- Double bonds
- C=C bonds and atoms bonded to them all lie in the same plane (they're planar)
- C=C cant rotate, not very flexible
- Untitled
- Alkenes show E/Z isomerism
- E isomer- opposite sides
- Z isomers- same side
- Cahn -Ingold-Prelog priority
- Assign a priority to the atoms attached to the C=C bond, to do this the higher atomic number is given more priority
- To work out which isomer you have just look at how the two priority groups are arranged (on both sides)
