Question

Explain the combustion and substitution reaction of carbon compounds by taking methane as example.Write the chemical equations for the above reactions.Can methane be subjected to addition reaction ?Give reason?

Answer 1

Answer:

Combustion: CH4+O2--> H2O +CO2+ HEAT

SUBSTITUTION: CH4 + Cl --> in presence of sunlight CH3Cl + HCL

Answer 2

Answer:

Combustion reaction:

CH4 +O2 ->(on heating) CO2 + H2O + Heat and light

Substitution reaction:

CH4 + Cl2 ->(sunlight) CH3Cl + HCl

Addition reaction is used to add hydrogen to unsaturated hydrocarbons. As methane is a saturated compound, it cannot be subjected to addition reaction.

Hope it helps.
