The study of the compounds of carbon Over 16 million compounds have been iden:ed about 1000 new ones are iden:ed each day! studies molecules actually present in living things
Brown, Foote and Iverson, Organic Chemistry Clayden et . al. 2001
-
Solomons and Fryhle, Organic Chemistry
Big bang Early atmosphere (CH4, CO2, H2O, NH3, H2)
Simple organic
compounds
Amino acids, simple sugars, purines and pyrimidines
Biological molecules
Proteins, carbohydrates, DNA and RNA
-
organic compounds known from nature -- essen:al oils that could be dis:lled from plants
structures were not yet known at the :me
Clayden et al., Organic Chemistry
-
Coal reservoir of chemicals in the 19th century produces tar upon burning, aroma:cs
Clayden et al., Organic Chemistry
Oil 20th century energy source e.g. methane, propane
-
21st century: search for natural products that can cure diseases, improve living condi:ons
synthesize organic materials that are cheaper and durable
create more ecient products and reac:ons
Clayden et al., Organic Chemistry
-
coined the terms organic and inorganic
Invented the system of chemical symbols s9ll used today
published the rst list of accurate atomic weights
proposed the idea that atoms carry an electric charge.
puried Ce, Se, Si, Th, Ti, and Zr Bruice, Organic Chemistry
-
INORGANIC derived from the atmosphere of mineral kingdom
unchanged by heat lacks vital force (dis9nc9ve spirit)
usually ionic in nature
ORGANIC derived from animal or vegetable
permanently changed by heat
cannot be synthesized in the lab
molecular

two dierent chemicals could have the same molecular formula
developed methods of purifying Al & Be
