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.
How many chlorinated products are possible for methane?
Four constitutionally isomeric dichlorinated products are possible, and five constitutional isomers exist for the trichlorinated propanes.
What are the products formed by the chlorination of methane in diffused sunlight?
Methane reacts with chlorine in diffused sunlight, or when heated to 600K to give chloromethane. Methyl chloride is formed by the substitution of hydrogen atom of a methane molecule, by a chlorine atom. This type of reaction is known as substitution reaction and the product formed is known as substitution product.
How does methane react with 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.
Why chlorination of methane is not possible in dark?
methane can form free radicals in presence of sunlight only. … Hint: Chlorination of methane is a free radical substitution reaction. Chlorine is not able to convert into free radicals in the dark, so the reaction doesn’t happen. Hence, presence of sunlight is must for the reaction to occur.
Why Ethane is produced in chlorination of methane?
In the termination step, we can see that two methyl free radicals combine and produce ethane. Thus, ethane is formed during the formation of chloromethane by chlorination of methane because two methyl free radicals may combine during chlorination to give ethane.
How many mono chlorinated products are formed by the chlorination of methane in presence of sunlight?
Free Radical Halogenation Of Methane And Ethane Can Give Only One Monochlorinated Product. In the last post we discussed mono-chlorination of methane. It’s easy to talk about this reaction since all the hydrogens are equal. No matter which hydrogen you replace, you get the same product (CH3Cl).
What is the action of Cl2 on methane?
Complete answer: When methane reacts with chlorine a substitution reaction occurs and the organic product is chloromethane. CH4+Cl2→CH3Cl+HCl. But the reaction doesn’t stop there, and further reactions go on where all the hydrogens in the methane get replaced by chlorine atoms.
What is halogenation of methane?
The halogenation of methane is a gas-phase reaction with a homolytic bond breakage. Therefore, the activation energy of the halogenation is equivalent to the association energy of the respective halogen. The kinetics of methane halogenation can easily be described, as the association energies of all halogens are known.
Which reacts explosively with methane?
Methane reacts violently with OXIDIZING AGENTS (such as PERCHLORATES, PEROXIDES, PERMANGANATES, CHLORATES, NITRATES, CHLORINE, BROMINE and FLUORINE). Methane can react violently with boiling WATER and cold WATER. Liquefied Methane combined with liquefied OXYGEN can form an explosive mixture.
What does Cl2 stand for?
Chlorine gas consists of pairs of chlorine atoms bonded to one another (chemical symbol: Cl2).
