In this article, the author has explained Sources of organic compounds such as coal, plants, animals, and petroleum products.
Sources of organic compounds
Organic compounds are everywhere. The rich source of organic compounds in plants and animals. Due to the importance of organic compounds in the modern world, these are also being synthesized in laboratories on a large scale. There are four main sources of organic compounds.
- Plants and animals
- Natural gas
Let us discuss the main sources one by one in detail.
1: Plants and animals
First of all we will discuss about plants and animals
Plants and animals which are directly available to us are also a good source of the organic compound. Moreover, organic synthesis also helps us to have some new compounds. Plant and animal are the major sources of organic compounds from nature.
Let us know what is coal?
Coal is found in the Earth crust in the form of black deposits. These deposits are the remains of vegetable matter. This vegetable was buried under the surface of Earth millions of years ago.
Above 500 million years ago, due to high pressure and temperature, the vegetable matter changed into coal deposits. This happened due to the loss of moisture and elimination of gas like Hydrogen and oxygen.
What elements are present in the Coal?
In addition to carbon hydrogen and oxygen coal contains minor amounts of Nitrogen and sulfur. Some amount of water and mineral impurities are also there. Due to the bacterial and chemical action on wood it was converted into peat.
Various types of folds are as follows.
Classification of coal
Based on the percentage of carbon coal has been classified into four categories.
Anthracite black in color consists of 95% of carbon with a hard texture. Due to the high percentage of carbon, it is utilized as a fuel.
This is the most used full form of coal and is the most abundant one. When this coal is fractionally distilled it give 5 fractions.
This form of coal is used in power generating stations
Lignite coal brown in colour consists of 50 to 60% of carbon with high moisture content and soft texture.
Carbonization of coal or destructive distillation of coal
At first stage Bituminous coal is stored in iron retorts. It is heated in the absence of air between 2000 degree centigrade to 1400 degree centigrade. Following Chief products are obtained as a result.
Composition of Coal Tar
It is a liquid component of coal. It contains about 215 aromatic compounds. It is subjected to fractional distillation again and gives for fractions.
3: Natural gas
Natural gas is also found under the earth’s crust.
Composition of natural gas
Natural mostly consists of methane. The presence of Methane is 80 to 95%. It also contains a lot of Ethane propane and butane. These three hydrocarbons are also gases at room temperature. Moreover natural gas also contains CO2, H2S, and N2 gas.
How Natural gas is formed?
Natural gas is formed from the remains of the sea animals and plants. It is always associated with Petroleum. It is found in porous rocks in the earth crust.
Applications of natural gas
- Natural gas is mostly used as a fuel around the world
- It is used to produce carbon black which is a filler in the manufacturing of tires.
- It is one of the raw materials for the manufacturing of urea.
- It is utilized as an electricity source in the cement and Fertilizer industry
- It is used as a domestic fuel
Petroleum is a naturally occurring Brown and greenish-black viscous oily liquid which is obtained from the earth’s crust.
The word petroleum is derived from a Latin word which means Rock oil.
Chemical nature of Petroleum
Petroleum is a mixture of saturated hydrocarbon from C-1 to C-40. Anyhow small amounts of the same other compounds are also present. This compound contains nitrogen Sulfur and oxygen.
Origin of Petroleum
Petroleum is found in some parts of the world below The crust of the earth. Many theories have been proposed to explain the origin of petroleum in nature. Anyhow, none of the theories is complete in itself. Two old theories are as follows
Modern theory about the origin of petroleum
According to the modern theory it is believed that petroleum has biological origin. Petroleum is found due to the decay and decomposition of marine animals. The vegetable organisms of the Prehistoric forest have also been decayed and decomposed.
It is thought that the Prehistoric forest and sea animals got buried underground. This biological matter found very high pressure and temperature in the interior of earth for millions of years. This process is responsible for the composition under the influence of radioactive substances or by bacterial agents.
Deposition of Petroleum
The petroleum that produce gradually moved through the porous rocks under great pressure. Then it reach dude areas under the earth where it was surrounded by non porous rocks. Here it was selected as large reservoir.
The petroleum floats on water and is held under pressure along the natural gas.
Further at industrial scale cracking of petroleum results in different hydrocarbons for different uses.
What are the sources of organic compounds?
Organic compounds are chemical compounds that contain carbon and hydrogen atoms, and they can be found in a variety of sources, including plants and animals, fossil fuels, synthetic materials, and the environment. Some common examples of organic compounds include carbohydrates, proteins, fats, plastics, pharmaceuticals, and pesticides.
Explain how petroleum is source of organic compounds?
Petroleum is a fossil fuel that is formed from the remains of plants and animals that lived millions of years ago. It is a complex mixture of hydrocarbons and other organic compounds, including alkanes, alkenes, and aromatic compounds. When petroleum is extracted from the ground and refined, it can be separated into its individual components, which can then be used to make a wide variety of products, including fuels, plastics, and chemicals.
What is the source of organic material in coal?
Coal is a fossil fuel that is formed from the remains of plants that lived millions of years ago. The organic material in coal comes from the plants that were buried and preserved over time, undergoing chemical and physical changes as they were subjected to heat, pressure, and the absence of oxygen.
How can we obtain the organic compounds from natural sources?
Organic compounds can be obtained from natural sources through extraction, fermentation, synthesis, and harvesting. For example, essential oils can be extracted from plants using solvents, ethanol can be produced through the fermentation of sugars, and fruits and vegetables can be harvested for their organic compounds.
Which type of organic compounds are present in natural gas?
Natural gas is a fossil fuel that is composed primarily of methane, which is a simple hydrocarbon with the chemical formula CH4. Methane is the primary component of natural gas, but it also contains smaller amounts of other hydrocarbons, such as ethane, propane, and butane. These hydrocarbons are classified as alkanes, which are a type of saturated hydrocarbon with a straight chain of carbon atoms. Natural gas also contains trace amounts of other organic compounds, such as water, carbon dioxide, and nitrogen.
What can be derived from the organic compounds present in petroleum and natural gas?
Petroleum and natural gas are sources of a wide variety of organic compounds that can be used to produce fuels, plastics, chemicals, and pharmaceuticals. Fuels made from these compounds include gasoline, diesel, and heating oil. Plastics made from these compounds include polyethylene, polypropylene, and PVC. Chemicals made from these compounds include solvents, detergents, and fertilizers. Some pharmaceuticals made from these compounds include aspirin and penicillin.
