Question

explain the combustion and substitution reaction of carbon compounds by taking methane as an example. write the equation for the above reactions. can methane be subjected to addition reaction? give reason​

Answer 1

Combustion reaction

It is a type of reaction where generally all allotropic forms of carbon react (burns) with oxygen to give out CO₂ along with release of heat and light energy

Example: CH₄ + 2O₂ => CO₂ + 2H₂O + heat and light energy

Substitution reaction

It is a type of reaction where a halogen element such as Chlorine substitute hydrogen from hydro carbons in the presence of sunlight

Example: CH₄ + Cl₂ => CH₃Cl + HCl

Note: The following reaction occurs in the presence of diffused sunlight

=> Methane cannot be subjected to addition reaction because methane cannot form unsaturated compound i.e formation of Methene is not possible
