Question

3 Explain the combustion and substitution reaction of
Carbon Compounds by taking Methane as an example,
Write the chemical equations for the above reactions.
Can methane be subjected to addition reaction ?
I Give reason​

Answer 1

When electricity is passed through the aqueous solution of sodium or potassium salt of the monocarboxylic acid, the alkane is formed. This reaction is called Kolbe's electrolysis. Metal carbide like Aluminium carbide (Al4C3) or Berrylium carbide (Be2C) is treated with water, methane gas is formed

Answer 2

Combustion reaction

In this reaction, a reactant reacts with oxygen and undergoes oxidation to form oxides.

2Na + O2  →2NaO

Substitution reaction

In this reaction an atom or a group of atom of high reactivity in a molecule replaces an atom or a group of atom in another molecule of low reactivity.

CH3-CH3    +   Cl2     →   CH3-CH2Cl     + HCl

No, methane cannot undergo addition reaction as addition reaction takes place in alkenes and alkynes.

Explanation

The methane can undergo substitution reaction and cannot undergo addition reaction as there is single carbon in this molecule and hence lacks double or triple bond
