Organic Chemistry
2
What is Organic chemistry?
Historical “Organic” – derived from living organisms Compounds such as sugar, urea, starch Vitalism: natural products needed a “VitalForce” to create them Wöhler (1828) synthesis of urea Inorganic Organic
3
Organic Chemistry Today
The study of compounds and reactions involving carbon, regardless of source (Kekulé, 1861) Organic Chemistry: The chemistry of carbon and carbon-based compounds
4
Why should we care? Biochemistry Pharmaceuticals Industry Polymers
Explosives
5
Organic Chemistry in everyday life:
Smells & tastes: fruits, chocolate, fish, mint Medications: Aspirin, Tylenol, Decongestants, Sedatives Addictive substances: Caffeine, Nicotine, Alcohol, Narcotics Hormones/Neurotransmitters: Adrenaline, Epinephrine Food/Nutrients: Carbohydrates, Protein, Fat, Vitamins Genetics: DNA, RNA Consumer products: Plastics, Nylon, Rayon, Polyester

Dopamine
12
Dopamine. Dash Molecular formula
two lines = 4 electrons one line = 2 electrons Condensed molecular formula = C8H11NO2
13
Dopamine. Line-Angle Molecular formula
all nodes are carbon add hydrogens until there are 4 bonds to each carbon atom
14
Both structures represent the molecule dopamine but the bottom structure is simpler to draw.
