How is methane chlorinated?

The organic product is chloromethane. One of the hydrogen atoms in the methane has been replaced by a chlorine atom, so this is a substitution reaction. However, the reaction does not stop there, and all the hydrogens in the methane can in turn be replaced by chlorine atoms.

Which is a possible product for the chlorination of methane?

Depending on reaction conditions, the chlorination of methane yields dichloromethane, chloroform and carbon tetrachloride. In most hydrocarbons, more than one possible product exists depending on which hydrogen is replaced.

Which of the following is the major product of the chlorination of methane if a large excess of methane is used?

methyl chloride

What happens when chlorine is treated with methane?

Complete answer: When methane reacts with chlorine a substitution reaction occurs and the organic product is chloromethane. Having produced some chloromethane in no way can be prevented from being hit by chlorine radicals, and similarly for dichloromethane and trichloromethane.

Why is reaction between methane and chlorine?

With the excess of chlorine, all the four hydrogen atoms of methane are replaced by chlorine atoms to form carbon tetrachloride (CCl4). This reaction is considered as substitution reaction because hydrogen of methane is substituted by chlorine.

What happens when methane is burnt in air?

When methane burns in the air it has a blue flame. In sufficient amounts of oxygen, methane burns to give off carbon dioxide (CO2) and water (H2O). When it undergoes combustion it produces a great amount of heat, which makes it very useful as a fuel source.

What is the function of UV radiation during the reaction between chlorine and methane?

The splitting of the chlorine molecule into the 2 radicals requires UV light as this supplies the energy needed to break the covalent bond between the 2 chlorine atoms in the molecule. In the above reaction, the chlorine radical reacts with the first methane molecule to form a methyl radical and HCl.

Why is UV light needed for free radical substitution?

The role of the UV light The ultraviolet light is simply a source of energy, and is being used to break bonds. In fact, the energies in UV are exactly right to break the bonds in chlorine molecules to produce chlorine atoms.
