Question

Explain the confusion and substitution reaction of carbon compounds by taking methane as an example ​

Answer 1

Answer:

Combustion of Methane: $CH_{4} + 2O_{2} -> CO_{2} + 2H_{2} O$

-> When there is a reaction between one molecule of carbon compound like methane, in the presence of oxygen (two molecules of oxygen)

-> The product formed is one molecule of carbon dioxide and two molecules of water.

-> The balanced equation for the combustion of methane can be written as

$CH_{4} + 2O_{2} -> CO_{2} + 2H_{2} O$

Substitution reaction:

-> Methane undergoes a reaction with halogens in the presence of light which is called a substitution reaction.

In the presence of ultraviolet light, methane reacts with halogen molecules.

Ex: Methane + Chlorine → Methyl chloride + Hydrogen chloride

-> This reaction is referred to as a Substitution Reaction.

-> The reason is that methane is replaced by one molecule of the hydrogen atom from one molecule of a Chlorine atom.

-> Methane reacts with Chlorine molecule by substitution to produce one molecule of Methyl Chloride and Hydrogen Chloride (Hcl).
