History of Organic Chemistry

1780's

Scientist began to distinguish between organic compounds and inorganic compounds. Organic compounds were defined as compounds that could be obtained from living organisms. Inorganic compounds were defined as compounds that came from non-living sources.

Vitalism

The invention of a VITAL FORCE was needed to synthesize organic compounds. Therefore such synthesises could only take place in living organism and could not be placed in the test tubes and flasks of the laboratory.

VITAL FORCE THEORY = inorganic materials could be converted to organic materials in the presence of a vital force found only in living bodies.

1828 - Friedrich Wöhler

He synthesized the organic compound urea (a constituent of urine). Urea was synthesized by evaporating an aqueous solution containing the inorganic compound ammonium cyanate.

1828 - 1850

A number of clearly organic substances were synthesized from sources that were clearly inorganic. Vitalism died slowly and did not completely dissapear from scientific circles until 1850. August Kekule gave the science of organic chemistry its modern definition.

Definition of Organic Chemistry

Organic Chemistry is defined as the study of hydrocarbons (binary compounds of hydrogen and carbon) and their derivatives. Organic Compounds are compounds that have exhibit covalent bonding, low melting point, low boiling point, low solubility in water; high solubility in non polar solvent, it is flammable, the solutions are non-conductors of electricity. Chemical reaction are usually slow, it has exhibit isomerism.

Families of Organic Compounds

There are many kinds of Organic Compound Families. Some of them are Alkene, Arene, Alkyl Halide, Alcohol, Ether, Aldehyde, Ketone, Carboxylic Acid, Ester, Amine, Amide, Nitrile, Carboxylic Acid Halide, Carboxylic Acid Anhydride, Thiol, Sulfide.

But now, we will only discuss about ALDEHYDE & AROMATIC, do you wanna know more about it??
