Organic Chemistry: Carbon Compounds as Fuels

Carbon Compounds as Fuels:

General Overview

  • Organic chemistry deals with the study of carbon and its compounds.

  • These carbon compounds, including hydrocarbons and biomolecules, are considered as fuels.

  • Organic fuels can be broken down into further categories: fossil fuels and biofuels.

Fossil Fuels

  • Fossil fuels comprise of a large group of carbon-based compounds that occur naturally and can be burned to release energy. The main types are coal, oil, and natural gas.

  • These fuels are formed over millions of years from the remains of plant and animal life and are usually found underground.

  • Fossil fuels are non-renewable as they take a massive amount of time for formation.

Biofuels

  • Biofuels are fuels that are derived from biomass, often from plants. These can be in the form of liquid, gas, or solid.

  • Examples of biofuels are wood, biogas, ethanol, and biodiesel.

  • Biofuels are considered renewable as they can be produced from today’s plants and animal waste.

Combustion of Fuels

  • The combustion of hydrocarbons in oxygen produces carbon dioxide, water, and energy. This process is exothermic as energy is released.

  • Incomplete combustion, often due to insufficient oxygen supply, can produce carbon monoxide and soot which are harmful pollutants.

Environmental Impact of Fuel Combustion

  • Burning of fossil fuels results in the release of greenhouse gases such as carbon dioxide.

  • Excessive production and accumulation of these gases in the atmosphere can contribute to global warming and climate change.

  • Biofuels, on the other hand, are considered carbon-neutral as the carbon dioxide they release during burning is balanced by the carbon dioxide absorbed during the growth of the plants used for their production.

Hydrocarbons

  • Hydrocarbons are compounds composed of only carbon and hydrogen atoms.

  • Examples of hydrocarbons are methane, ethane, butane, which are components of natural gas and used in heating and cooking.

Advantages and Disadvantages of Fossil Fuel Use

  • Fossil fuels provide a large amount of energy, are easy to use, and are readily available.

  • Disadvantages include their non-renewable nature, contribution to pollution, global warming, and the destructive fossil fuel extraction process.
