v.3. The Chemical Dynamics: Exploring Combustion, Oxidation, and Reactions in Carbon Compounds

Combustion Reactions

  • Combustion means the burning of carbon or carbon-containing compounds in the presence of air or oxygen to produce carbon dioxide, heat and light.
  • 2CH3OH + 3O2 → 4H2O + 2CO2
  • Saturated hydrocarbons give a clean flame, while unsaturated hydrocarbons give a smoky flame. 
  • In the presence of limited oxygen, even saturated hydrocarbons give smoky flame.
  • Soot: It is a black substance formed by combustion or separated from fuel during combustion, rising in fine particles and adhering to the sides of the chimney or pipe conveying the smoke especially, i.e., the fine powder consisting chiefly of carbon that colours smoke. 

Oxidation

  • Oxidation is a chemical reaction that occurs in an atom or compound and results in the loss of one or more electrons.

Addition

  • The reactions in which two molecules react to form a single product having all the atoms of the combining molecules are called addition reactions.
  • The hydrogenation reaction is an example of the addition reaction. 
  • In this reaction, hydrogen is added to a double bond or a triple bond in the presence of a catalyst like nickel, palladium or platinum.

Substitution

  • The reaction in which an atom or group of atoms in a molecule is replaced or substituted by different atoms or groups of atoms is called a substitution reaction. 
    • In alkanes, hydrogen atoms are replaced by other elements.

Why do substances burn with or without a flame?

This is because a flame is only produced when gaseous substances burn. When wood or charcoal is ignited, the volatile substances present evaporate and burn with a flame in the beginning.

A luminous flame is seen when the atoms of the gaseous substance are heated and start to glow. The color produced by each element is a characteristic property of that element.
