WebbTypes of elimination reactions: E1 reaction: It involves unimolecular elimination. It is a two-step process: Ionization and deprotonation. Ionization: The C—H bond breaks to form a carbocation intermediate. Deprotonation: The H+ ion is removed to form the neutral molecule. E1 often takes place in 3° alkyl halides and some 2° alkyl halides.
