Chemical Properties of Chlorine Gas

  1. 1. CHEMICAL PROPERTIES OF CHLORINE CHAPTER 04 XII CHEMISTRY SIDRA JAVED
  2. 2. Chemical reactions of chlorine The chemical reactions of chlorine are of following types: 1. Oxidation reactions 2. Addition reactions 3. Substitution reaction 4. Auto oxidation - reduction reactions
  3. 3. Oxidation Reactions Cl2 is a strong oxidizing agent Due to high electronegativity it readily gains electrons and become negatively charged Cl2 + 2e- → 2Cl-
  4. 4. Oxidation Reactions Cl2 readily oxidizes other metals and nonmetals Zn + Cl2 → ZnCl2 Cu + Cl2 → CuCl2 2P + 5Cl2 → 2PCl5 H2 + Cl2 → 2HCl
  5. 5. Addition Reactions Cl2 directly combines with certain compounds to give addition products CH2=CH2 + Cl2 → CH2Cl-CH2Cl CO + Cl2 → COCl2 SO2 + Cl2 → SO2Cl2
  6. 6. Substitution Reactions Cl2 replaces one or more atoms from other compounds H2S + Cl2 → 2HCl + S 2KI + Cl2 → 2KCl + I2 CH4 + Cl2 → CH3Cl + HCl CH3Cl + Cl2 → CH2Cl2 + HCl
  7. 7. Auto Oxidation and Reduction Reactions Cl2 reacts with water to form Hydrochloric acid (HCl) and Hypochlorous acid (HOCl). In this reaction Cl2 is oxidized as well as reduced. Cl2 o + H2O → H+Cl- + H+O-2Cl+ Such reactions are called auto oxidation reduction reactions
  8. 8. Chlorine water Solution of chlorine in water is a strong oxidizing agent In this solution HOCl act as oxidising agent due to +1 oxidation state of Cl Bleaching action of Chlorine is due to same reason. Cl2 forms HOCl with water which then oxidizes colored compound to colorless less compound.
  9. 9. Importance of Chlorine ❏ Manufacture of organic solvents such as CCl4 , CHCl3 etc ❏ Manufacture of vinyl chloride which is used in preparation of plastics (PVC) ❏ Used in preparation of Pesticides such as DDT, Hexachlorocyclohexane ❏ Manufacturing of synthetic rubber ❏ Used as a bleaching agent for cotton, rayon, wood pulp etc. ❏ Used in sterilization of drinking water ❏ Used in layer test for detection of halogens.
