What is Carbon Disulfide?

The carbon disulfide chemical formula is CS2. Carbon disulfide is also spelt as carbon disulphide. It is a colourless volatile liquid, which is used frequently as a building block in organic chemistry. Being the industrial and chemical non-polar solvent, the formula of carbon disulfide carries various chemical properties, which we will discuss on this page.

Along with this, we will have a look at the molecular formula of carbon disulfide, the structure to understand the carbon disulphide formula.

Now, let’s have a look at the basic reaction for the carbon disulphide formula:

CS2 is a highly inflammable volatile liquid. Its combustion produces sulfur dioxide by reacting with atmospheric gas, i.e., oxygen. Therefore, according to the ideal stoichiometry, the following reaction undergoes:

CS2(l) + 3 O2(g) → CO2(g) + 2 SO2(g)

Here, one mole of CS2 reacts with three moles of O2 to produce CO2 and two moles of SO2.

Conclusion

CS2 is a highly reactive volatile liquid, which is formed as;

C + 2S → CS2

Being a highly flammable gas, it must be stored in a refrigerator at lower temperatures.

FAQs on Carbon Disulfide Formula

1. Determine The Product Formed By the Chlorination of CS₂.

Ans: Chlorination of CS helps in carbon tetrachloride formation, the following reaction undergoes:

CS₂ + 3 Cl₂ → CCl₄ + S₂Cl₂

(Carbon Tetrachloride)

The above reaction proceeds via the intermediacy of thiophosgene, CSCl₂.

2. How Do You Prepare Carbon Disulphide?

Ans: Following is the carbon disulfide preparation reaction:

At a lower temperature of 600 °C, a natural gas as the carbon source in the presence of silica gel or alumina catalysts the following reaction takes place:

2 CH₄ + S₈ → 2 CS₂ + 4 H₂S

(Methane) (Hydrogen Sulfide)
