WebTopic Questions 3.3.1 Halogenoalkanes Download notes Substitution & Elimination Reactions of Halogenoalkanes Halogenoalkanes are much more reactive than alkanes due to the presence of the electronegative halogens The halogen-carbon bond is polar causing the carbon to carry a partial positive and the halogen a partial negative charge WebThe Halogens – Reactions with Halogens. As the halogens become less reactive down the group, their oxidising ability decreases. Remember that oxidation is a gain of electrons. …

WebPast papers, summary notes and past exam questions by topic for AQA, CIE, Edexcel, OCR and WJEC Chemistry A-levels, International A-levels, GCSEs and IGCSEs WebHalogens react with metals by accepting an electron from the metal atom to become an ion with 1- charge Eg. Ca (s) + Cl2 (g) → CaCl2 (s) consisting of Ca2+ and 2Cl- ions Halogens are therefore oxidising agents: Halogens oxidise the metal by removing an electron from the metal (the oxidation number of the metal increases) stainless steel sinks with faucets
