Organic Chemistry Meaning

What is organic chemistry:

Organic chemistry studies the chemical reaction, properties and behaviors of structures based on carbon molecules and their compounds.

The importance of organic chemistry lies in the molecular knowledge of carbon since it is present in all beings on planet Earth interacting with the environment, such as in the carbon cycle.

Inorganic chemistry or also called mineral chemistry studies bodies that do not contain carbon in their molecules.

Organic nomenclature

The nomenclature used for organic chemistry today is a system implemented by the International Union of Pure and Applied Chemistry (IUPAC) also called systematic nomenclature.

The organic nomenclature is basically composed of a prefix and a suffix. The prefix determines the number of carbon atoms that exist being the following:

  • 1 carbon: met-
  • 2 carbons: et-
  • 3 carbons: prop-
  • 4 carbons: but-
  • 5 carbons: pent-
  • 6 carbons: hex-
  • 7 carbons: hept-
  • 8 carbons: oct-
  • 9 carbons: non-
  • 10 carbons: dec-

The organic nomenclature suffix determines the class of organic compound. Hydrocarbons, for example, are organic compounds that only contain carbon and hydrogen in their molecule and depending on the type of hydrocarbon the suffix will be different:

  • Alkane suffix: -ano. Example: methane, propane.
  • Suffix alkenes (carbon double bonds): -ene, -diene, -triene and so on.
  • Suffix alkynes (triple carbon bonds): -ino, -diino, -triino and so on.
  • Suffix alkenes and compound alkynes with double and triple carbon bonds: -enines. Example: ethene, propene and ethyne. They are also known in common nomenclature as ethylene, propylene and acetylene.
