Combustion : A reaction in which substance is heated in the presence of air or oxygen.
During the reaction, carbon present in all allotropic form undergoes combustion to produce heat and light.
Example : CH4 + 202 ----> Co2 + 2H20 + Heat and light.
Substitution : A reaction in which substitution of an atom or a group of atoms in an organic compound takes place by amother atom or group of atoms is called substitution reaction.
Example : CH4 + Cl2 ----> CH3Cl + HCl.
No, methan can not be subjected to addition reaction because it is saturated carbon compound. Only unsaturated carbon compound undergoes addition reaction in presence of nickel or palladium catalyst to form saturated carbon compound.
