Explain why the C=C bond is attacked by electrophiles.

In the subtopic Structure, bonding and reactivity, this AQA A-Level Chemistry 7405 learning objective focuses on explain why the C=C bond is attacked by electrophiles. It belongs to Alkenes, so revision should stay anchored to this exact subtopic rather than drifting into a generic GCSE-level chemistry summary. Approved keywords to use include electrophile. Electrophile. means a species that is attracted to electrons and can accept an electron pair, often attacking the C=C bond in alkenes Avoid the mistake of students often think that the C=C bond is attacked by electrophiles because it is simply a double bond without understanding the role of electron density; instead, the C=C bond has a high electron density due to the presence of pi bonds, which attracts electrophiles. This attraction occurs because electrophiles are electron-deficient species that seek out areas of high electron density. As a result, the C=C bond is susceptible to attack, leading to the formation of new products through electrophilic addition reactions For exam answers, remember that the presence of a double bond (C=C) in alkenes makes them electron-rich, which attracts electrophiles
