Question

Discuss about combustion,oxidation and additional reactions of hydrocarbon

​

Answer 1

Answer:

COMBUSTION REACTION:

When Carbon and its compounds burn in the presence of Oxygen (or air), they give CO2, heat and light.The process of burning carbon and its compounds in excess of oxygen for the release of heat and light (energy) is known as combustion.

                                     C + O2 ⇨ CO2 + Heat + Light

OXIDATION REACTION:

In a combustion reaction, carbon compounds are oxidized in the presence of oxygen. Though combustion is generally an oxidation reaction, not all oxidation reactions are combustion reactions. Oxidation is also carried out by using oxidizing agents (Oxidants).

Oxidizing agents, also referred as Oxidants are substances that oxidize other substances while undergoing reduction themselves.

ADDITION REACTIONS:

Unsaturated organic compounds, like alkenes and alkynes, contain multiple bonds (C=C, C≡C) between their carbon atoms.They undergo addition reactions to become saturated in nature.

The formation of larger molecules by addition of more radicals is known as addition reaction.During an addition reaction of unsaturated organic compounds, a reagent takes place at the double bonded or a triply bonded carbon atoms.  

                          CH2=CH2 + H2 + (Nickel catalyst) ⇨ CH3−CH3

hope this helps!
