Electrophilic addition is one of the most important mechanisms in IAL Chemistry, and examiners love testing it for both short-answer and long-answer questions. In this video, we break down every step clearly — partial charges, mechanism arrows, heterolytic fission, carbocation formation and the final product. If you master this mechanism now, you’ll secure marks that most students lose unnecessarily. Ideal for Unit 1 Organic Chemistry (Edexcel IAL). #ialchemistry #edexcelchemistry #alevelchemist
