Answer the following:

Name the compound of chlorine

1. Which is an anesthetic?

2. Which is used as a refrigerant?

3. Which is a disinfectant?

4. Which is used to make pipes and tube?

5. which liberates chlorine on exposure to air.

1. Chloroform is a compound of chlorine which is used as an anesthetic. Anesthetic is a drug by which person does not feel pain during surgery or operation. The chemical formula of chloroform is CHCl₃ and it is colorless. Nowadays it is very less used as an anesthetic as because its effects on the body can be serious, resulting in damage to both the liver and the kidneys.

2. chlorofluorocarbons (CFC) are a compound of chlorine which is used as a refrigerant. A refrigerant is a substance/fluid used in refrigerators or heat pump. CFC has some harmful effects on the environment as it leads to global warming and ozone layer depletion.

3. Sodium hypochlorite (NaoCl) and Calcium hypochlorite are used as a disinfectant. Disinfectant is a chemical which kills the bacteria or microorganisms. Sodium hypochlorite is a yellowish liquid and using sodium hypochlorite, disinfection is achieved at low concentrations of chlorine in water and sodium has no effect on water. Calcium hypochlorite is available as white powder or tablets so it is dissolved in warm water.

4. PVC (polyvinyl chloride) is a chlorine compound used to make

pipes and tubes. Chlorine and ethylene gas react together to form vinyl chloride at high temperature then vinyl chloride forms PVC by polymerization. In polymerization small molecules (vinyl chloride) join together to make very long molecules like PVC.

5. Bleaching Powder liberates chlorine on exposure to air. Its chemical formula is calcium oxy-chloride (CaOCl₂) and it is a yellowish powder. When bleaching powder is exposed to air, it reacts with carbon dioxide of surrounding to form chlorine gas and calcium carbonate. Its chemical equation is:

CaOCl₂ + CO₂→ CaCO₃ + Cl₂
