Definition of organic and inorganic compounds
The proper definition of organic and inorganic compounds is very complicated. But the previous definition of organic compounds is the substances produced from living organisms and inorganic compounds are the substances which were not prepared from living organisms. Although the list of organic compounds such as sugar, starch, alcohol, resins, indigo, methane, etc known from the earliest times but the formula of these compounds unknown.
But very little progress in their chemistry courses until about the beginning of the eighteen century.
In 1675, Lemery published a famous scientific journal, Cours de Chemie. They divided organic substances from natural sources into three classes.
- Organic compounds from mineral
- Compounds from plant namely vegetables
- Organic compounds from the animal
