Organic Chemistry - Some Basic Principles and Techniques

Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.

Importance of Organic Chemistry:

Organic chemistry is applicable in a variety of areas including-

  • Medicines: Example- Aspirin which is a headache medicine and Ibuprofen is a painkiller, both are organic compounds. Other examples include paracetamol.
  • Food: Example- Starch which is a carbohydrate is an organic compound and a constituent of rice and other grains. It is the source of energy.
  • Clothing: Example- Nylon, Polyester and Cotton are forms of organic compounds.
  • Fuels: Examples- Gasoline, Petrol and Diesel are organic compounds used in the automobile industry at large.
