Question
Write short note on tetra chloromethane (CCL4) ### Write short note on Carbon tetra chloride.

Answer

→ It is produced in large quantities for use in the manufacture of refrigerants and propellants for aerosol cans.
→ It is also used as feedstock in the synthesis of chlorofluorocarbons and other chemicals, pharmaceutical manufacturing, and general solvent use.
→ Until the mid 1960s, it was also widely used as a cleaning fluid, both in industry, as a degreasing agent, and in the home, as a spot remover and as fire extinguisher.
→ There is some evidence that exposure to carbon tetrachloride causes liver cancer in humans.
→ The most common effects are dizziness, light headedness, nausea and vomiting, which can cause permanent damage to nerve cells.
→ In severe cases, these effects can lead rapidly to stupor, coma, unconsciousness or death.
→ Exposure to CCl4 can make the heart beat 4 irregularly or stop. The chemical may irritate the eyes on contact.
→ When carbon tetrachloride is released into the air, it rises to the atmosphere and depletes the ozone layer.
→ Depletion of the ozone layer is believed to increase human exposure to Depletion of the ultraviolet rays, leading to increased skin cancer, eye diseases and disorders, and possible disruption of the immune system.
