Why bromination of alkane is slower than chlorination?

Bromination of alkanes occurs by a similar mechanism, but is slower and more selective because a bromine atom is a less reactive hydrogen abstraction agent than a chlorine atom, as reflected by the higher bond energy of H-Cl than H-Br.

Why iodine does not react with methane?

For the radical halogenation of methane, fluorine is the most reactive and iodine is the least reactive. In the case of Iodine the energy of activation is so high that Iodination of methane does not occur.

Why is iodination of methane reversible process?

Answer : Methane reacts with iodine to give methyl iodide (iodomethane) and hydrogen iodide (HI). Hydrogen iodide being a strong reducing agent converts iodomethane back to methane.

Why is chloromethane more reactive than methane?

Explanation: In chlorobenzene the chlorine atom shows its inductive erect (-I) more than its resonance effect (+R) . In chloromethane the (-I) effect of chlorine made the hydrogen atoms of methane more acidic which made chloromethane more reactive.

Is iodine more selective than bromine?

The fluorine radical is the most reactive of the halogen radicals, and it reacts violently with alkanes. In contrast, the iodine radical is the least reactive of the halogen radicals. Bromine radical is less reactive and more selective.

Does methane react with iodine?

Iodine, on the other hand, does not react with methane. The reaction entropy of methane halogenation is approximately zero, since two molecules of gaseous products are formed from two molecules of gaseous starting products in the reaction.

What happens when methane is treated with iodine in presence of an oxidizing agent?

Iodine reacts with methane reversibly. When iodine reacts with methane, it gives methyl iodide and hydrogen iodide which is a strong reducing agent and it can convert to iodomethane back to methane.

When methane is chlorinated Among the products found are traces of chloroethane how is it formed?

3) Termination: 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.

What happens when methane undergoes chlorination?

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