Organic Chemistry Flashcards
What gave rise to Organic chemistry
Friedrich Wöhle’s Experiment
It was a serendipitous one (unexpected, good fortune)
Organic chemistry
The chemistry of carbon and it’s compounds
Organic compounds most often contain one or more of the following elements
..oxygen
..nitrogen
..phosphorus
..any of the halogens
The following are excluded from the list of organic compounds
..Sulphides
..oxides of carbon
..cyanate
..hydrogen carbonates
..metallic carbonates
..The first organic compound to be synthesized?
..What year?
..By who?
..Urea
..1828
..By a German scientist called Friedrich Wöhler
How did Friedrich wöhler synthesize urea
He did so by
.. HEATING ammonium cyanate(NH⁴NCO) (inorganic) in a test tube to produce Urea
Formula representation of synthesis of Urea
NH⁴NCO –> NH²CONH²
<–
Ammonium Urea
Cyanate
Vital force theory
Organic compounds of substances can only be obtained from organic materials and not inorganic materials
How was the vital force theory dispelled
It was dispelled through Friedrich wöhler’s experiment which showed that an inorganic compound ammonium cyanate gave rise to an organic compound urea
Uniqueness of carbon
..Catenation
..Tetracovalency: tetrahedral structure and covalent character
..ability to form multiple bonds between itself and with atoms of certain other elements
Chains and rings can possess ?
*Branches… Protrusions with no interconnection
*Crosslinks.. bonds holding chains of atoms together, there is interconnection to form 3d structures
