Question

The combustion and substitution reaction of carbon compound by taking methane

Answer 1

Answer: reaction of some element or compound with oxygen to give heat and light is known as combustion example :CH4+O2__CO2+H2O, here Methane is reacted with oxygen to give carbon dioxide and water along with heat and light energy this is combustion of Methane

Substitution reaction reaction in which chlorine is added to hydrocarbon in the presence of Sunlight where it displaces hydrogen atoms one by one is known as substitution reaction as one type of atom takes place the other type of atom.

Example : CH4+Cl___CH3Cl+HCl

here chlorine has displace hydrogen from Methane hence it is substitution reaction.

Explanation:

Answer 2

Hey mate!

here is ur answer

1. Reaction of some elements or compound with oxygen to give heat and light is known as combustion

Ex : CH4 + O2 => CO2 +H2O

    2. Substitution reaction in which chlorine is added to hydrocarbon in the pressure of sunlight where it displaces hydrogen atoms one by one is known as substitution reaction

Ex : CH4 + Cl => CH3Cl + HCl

Here chlorine has displace hydrogen from methane hence it is substitution reaction
