Question

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

Answer 1

Answer:

Explanation:

• Carbon, in all its allotropic forms., burns in oxygen to give carbon dioxide along with the release of heat and light. This is known as Combustion reaction.

        Ex:   $CH_{4} + O_{2}$  ⇒ $CO_{2} +H_{2} O$$+ heat + light$

• In a very fast reaction, if one type of atom or group of atoms takes the place of another, it is known as a Substitution reaction.

        Ex:  $CH_{4} + Cl_{2}$   ⇒ $CH_{3} Cl_{} +HCl_{}$  (in the presence of sunlight).

• Methane is a saturated hydrocarbon it has all single bonds hence it cannot be subjected to addition reaction. Only unsaturated hydrocarbons add oxygen through oxidising agents to form saturated hydrocarbons.
