The idea that organic compounds arise only in organisms, was disproved when chemists synthesized these compounds

The view that all natural phenomena are governed by physical and chemical laws

organic molecules consisting of only carbon and hydrogen (fats have hydrocarbon components); can also undergo reactions that release large amount of energy (reacts vigorously w/ oxygen)

special class of hydrocarbons (ex: Benzene C₆H₆), have a smell, atoms arranged in a ring; used to produce polyester and nylon (industrial uses); aromatic amino acids: Phenyalanine, Tryotophan, Tyrosine

compounds with same molecular formula but different structure and properties

same covalent arrangements but differ in arrangements

different covalent arrangements of their atoms

isomers that are mirror images of each other

primary used for treatment of anti-nausea and as a sedative; enantiomer caused birth defects
