What is the action of chlorine on CS2
Solution
We know that CS2 is a volatile colourless liquid. It is called carbon disulphide. The structure of CS2 is .
(Carbon has 4 valence electrons, Sulphur has 6 valence electrons. In CS2 , there are 2 Sulphur atoms, so 12 valence electrons. Thus, the total electrons is 16). Now, there is a double bond in CS2 and 2 lone pairs on each Sulphur atom. It is used as a chemical non-polar solvent. It belongs to a class of inorganic compounds known as non-metallic sulphides. It is used as a building block in organic chemistry.
Complete step by step answer:
We know that chlorine is a halogen. Cl2 molecules when reacts with sodium atom produces sodium chloride
When sulphur and carbon are combined at high temperatures, carbon disulphide or carbon disulfide is formed.
C+2S→CS2
Carbon disulphide can be produced from volcanic eruptions also.
We know that chlorine molecule is used as a chlorinating agent, to add chlorine to molecules.
When chlorine is treated with carbon disulphide, we get carbon tetrachloride.
CS2+3Cl2→CCl4+S2Cl2
We could see that chlorine replaces the sulphur in carbon disulphide.
Now, on adding Cl2 , it gets chlorinated and all the lone pairs on chlorine are satisfied by a chlorine atom, forming carbon tetrachloride.
Thus, the action of chlorine on CS2 is the formation of carbon tetrachloride CCl4
Note:
We know the uses of the product Carbon Tetrachloride of this reaction. Chlorine is a better leaving group. It is used as a chlorine source in many reactions. Freons which are used in AC and refrigerators are made using CCl4 . It is used in fire extinguishers as it has a high melting point and low boiling point. Prolonged exposure can cause so much damage to humans.
