Importance of Organic Chemistry

Organic chemistry is a field of chemistry that studies the structure, characteristics, and reactions of organic compounds, which have carbon-carbon covalent bonds. Physical and chemical characteristics are studied, as well as chemical reactivity, to better understand their behaviour. The study of organic reactions covers the chemical synthesis of natural products, medicines, and polymers, as well as the laboratory and theoretical (in silico) study of individual organic molecules.

Organic molecules are the basic components of all life on Earth and make up the vast majority of known chemicals. Many commercial goods, such as medicines, petrochemicals, and agrichemicals, and also products derived from them, such as lubricants, solvents, plastics, fuels, and explosives, are made from them.

Classification of organic compounds

Functional groups

Functional groups are important in organic chemistry because they may be used to classify structures and predict characteristics. A functional group is a molecular module whose reactivity is expected to be the same in a variety of molecules, within certain limits. The chemical and physical characteristics of organic compounds can be significantly influenced by functional groups. Functional groupings are used to classify molecules.

Aliphatic compounds

According to their saturation state, aliphatic hydrocarbons are grouped into three types of homologous series: alkanes, alkenes, and alkynes.

The rest of the group is divided according to functional groups present. Straight-chain, branched-chain, and cyclic compounds are all examples of such compounds. In petroleum chemistry, features like the octane number or cetane number are affected by the degree of branching.

Aromatic compounds

Conjugated double bonds are found in aromatic hydrocarbons. This indicates that every carbon atom in the ring is sp2 hybridized, which increases the ring’s stability. The most famous example is benzene, whose structure was suggested by Kekulé, who was the first to propose the delocalization or resonance principle to explain it.

Heterocyclic compounds

The features of the cyclic hydrocarbons are again altered if heteroatoms are present, which can exist as either substituents connected externally to the ring (exocyclic) or as a member of the ring itself (endocyclic). In the latter situation, the ring is referred to as a heterocycle. Oxygen, sulfur, or nitrogen are the most prevalent heteroatoms in heterocyclic molecules, with the latter being particularly abundant in biological systems.

Heterocycles can be found in a variety of items, including aniline dyes and drugs. They’re also found in a variety of biochemical compounds like alkaloids, vitamins, steroids, and nucleic acids.

Importance of Organic Chemistry

Organic chemistry is significant because it is the study of life and all of its chemical reactions. Doctors, veterinarians, dentists, pharmacologists, chemical engineers, and chemists are among the professionals who apply the understanding of organic chemistry.  The relevance of organic chemistry may be seen in the huge array of substances we utilize on a daily basis. Some common uses of Organic compounds are-

1. Food: Carbohydrates, proteins, and fats are the carbon compounds that form the basis of food materials.  Vitamins are also organic in nature.
2. Cleansing agents: Organic solvents are frequently used in industries and laboratories to remove contaminants. For example, in the extraction of drugs from plants, petroleum ether is used to separate the fatty materials from the pulp. As a result of organic chemistry’s knowledge of polarity, solubility, and partition factors, solvents are used to separate components for better use.
3. Sterilizing agents:- The majority of sterilizing and disinfecting agents, such as phenol and formaldehyde, are carbon compounds. They can kill microorganisms and even human body cells due to their characteristics such as solubility and pH. These destroy bacteria and other germs by dissolving the cell wall or damaging the protein layer, among other things.
4. Analytic substances:- The majority of the substances we use, such as medications and insecticides, are tested qualitatively and quantitatively using various titrations, chromatography methods, and spectrophotometry. In this case, the reagents used, such as acids or bases or reductive oxidative species, are organic in nature. Furthermore, organic chemistry is responsible for the development of endpoint indicators in titration.
5. Valuables:- Carbon compounds, interestingly, are proven to be very precious, durable, and toughest in the world. Diamond and graphite are both carbon-only compounds that contain no other elements. They’re both widely used and expensive.  Petroleum is the world’s other most valuable resource for meeting global fuel demands. These petroleum products are further diversified for a variety of applications.

Importance of Heterocyclic Compounds

Applications of Aromatic Heterocycles in Agriculture-Pests such as rodents, insects, germs, and weeds consume or destroy the majority of the food meant for humans. Biological plant protection techniques have a lot of potential, but chemical control is still the most prevalent way. Pesticides, which include herbicides (weed killers), insecticides, fungicides, and rodenticides, are used to control pests by chemical means. Plant growth stimulators and regulators are also quite important. Because heterocyclic chemicals are involved in so many biological systems, it’s no surprise that they make up the bulk of pesticides.

Fluorescence – Fluorescence is defined as the absorption of radiation by atoms or molecules, followed by the immediate emission of electromagnetic radiation when the particles move to lower energy states. Fluorescent heterocyclic compounds have an important role in a variety of fields, including emitters for electroluminescence devices.

Pharma – Heterocycles are common fragments of the great majority of commercially available medicines, and they serve an important role in modern drug synthesis. Common usage of Heterocyclic compounds is found in Antimalarial medicines, Anti-Inflammatory medicines etc.

Conclusion

Organic chemistry is the study of structure, characteristics, composition, reactions, and preparation of carbon-containing compounds. The most common components in organic compounds are carbon and hydrogen, although they can also contain a variety of additional elements (e.g., nitrogen, oxygen, halogens, phosphorus, silicon, sulphur). Organic chemistry is a very creative field in which scientists are able to develop and explore molecules and compounds. Organic chemists devote a significant amount of their work to the development of new chemicals and the expansion of existing ones.   Organic compounds make up at least a portion of many modern materials. They’re essential for economic development and are fundamental to biochemistry, biotechnology, and medicine.
