How is CCl4 prepared from CH4?

Carbon tetrachloride was originally synthesized by the French chemist Henri Victor Regnault in 1839 by the reaction of chloroform with chlorine, but now it is mainly produced from methane: CH4 + 4 Cl2 → CCl4 + 4 HCl.

What happens when chlorine reacts with methane?

If a mixture of methane and chlorine is exposed to a flame, it explodes – producing carbon and hydrogen chloride.

How do you make CCl4?

Carbon tetrachloride was originally synthesised in 1839 by reaction of chloroform with chlorine, but the most common synthesis is now chlorination of carbon disulfide at 105 to 130 °C: CS2 + 3Cl2 → CCl4 + S2Cl. CCl4 can also be prepared from methane via the reaction: CH4 + 4 Cl2 → CCl4 + 4HCl.

What type of reaction is CH4 Cl2?

When methane is mixed with chlorine in the presence of sunlight, a free radical substitution reaction occurs. In the initiation step, Cl2 undergoes homolytic fission in sunlight to form Cl atoms, which have unpaired electrons thereby making them a very reactive species known as radicals.

When chlorine gas reacts with methane CH4 carbon tetrachloride and hydrochloric acid are produced?

Methane gas (CH4) reacts with chlorine gas (Cl2) to produce liquid carbon tetrachloride (CCl4) and hydrogen chloride gas (HCl). The balanced chemical equation for the reaction is as follows: CH4(g) + 4 Cl2(g) → CCl4(l) + 4 HCl(g).

Does carbon react with chlorine?

carbon react with chlorine to form ccl4 .

How ch4 is formed?

Hydrogen atom has one electron and needs one more electron to get stable electronic configuration of nearest noble bas, helium. Therefore, one atom of carbon shares its four electrons with four atoms of hydrogen to form four covalent bonds.

What is the major product of chlorination of methane when chlorine is used in excess?

Note: The chlorination of methane also takes place in thermal conditions. If the amount of chlorine is limited then the major product is methyl chloride i.e. \[C{H_3}Cl\]. If the amount of chlorine is unlimited then only the major product is carbon tetrachloride i.e. \[CC{l_4}\].

Is the reaction between methane and chlorine endothermic?

If more energy is put into a reaction than is given off, the ΔH is positive, the reaction is endothermic and not energetically favorable. Since, the ΔH for the chlorination of methane is negative, the reaction is exothermic.

Why is the reaction between methane and chlorine considered a substitution reaction?

When methane reacts with chlorine, the hydrogen atom of methane is replaced by chlorine atom step by step and hence it is termed as substitution reaction.
