Edexcel IAL Chemistry AS 5.6 Electrophilic addition mechanisms
Start the first arrow at the carbon–carbon pi bond, show bond fission and the charged intermediate, then direct a lone pair from the negative ion to the carbocation.
How this is tested
- Draw curly arrows from the alkene pi bond to an electrophile and from the broken bond.
- Show carbocation intermediates, charges, dipoles and nucleophile lone-pair attack.
- Explain major products through the relative stability of possible carbocations.
