Answer» Correct Answer - Option 1 : Carbon tetrachloride
Carbon tetrachloride is an organic compound with the chemical formula CCl4. This compound is often classified as a polyhalogenated organic compound since it consists of a carbon atom which is attached to more than one halide functional group. In the past, this compound was widely used in cleaning agents. It was also used in fire extinguishers and was known to serve as a precursor to several refrigerants. However, the use of this compound has been phased out by several governments due to its toxicity. The inhalation of large quantities of carbon tetrachloride can cause serious damage to vital organs like the kidney and liver. It can also have negative effects on the central nervous system (CNS). Furthermore, prolonged human exposure to carbon tetrachloride often results in death. In the hydrocarbon for example methane if all the H atoms are replaced with both Cl and F are termed as chlorofluorocarbons (cfc's).They are very light in weight and are used in refrigerators, air conditioners, aerosol sprays and in making foams etc. - To prepare chlorofluorocarbons, the liquid mostly used is CCI4. The balanced chemical equation of the reaction is: CCI4+2HF(l)→CCI2F2(g)+2HCI.
- Hence, among the given options, the correct answer is option a carbon tetrachloride.
