Pearson Edexcel IAL Chemistry AS 5.3 E-Z naming
Pearson Edexcel IAL Chemistry AS 5.3 E-Z naming
Practise E-Z naming by assigning priorities at C=C bonds, choosing correct IUPAC names and drawing named geometric isomers.
How this is tested
- assign E or Z by comparing the highest-priority group on each carbon of the C=C bond
- choose the correct IUPAC name for halogenated alkenes with locants and E-Z labels
- explain when E-Z naming is needed because cis-trans naming cannot describe the structure
