Cards

Term
organic chemistry
Definition
the study of carbon compounds and the chemistry of living things
Term
organic molecules
Definition
A molecule with a basic skeleton made up of carbon atoms
Term
vitalism
Definition
the belief in a life force outside the jurisdiction of physical and chemical laws
Term
mechanism
Definition
the belief that all natural phenomena, including the processes of life, are governed by physical and chemical laws
Term
hyrdocarbons
Definition
molecules with carbon and hydrogen only
Term
isomer
Definition
compounds with the same molecular but different structural formulas
Term
structural isomer
Definition
differ in covalent arrangement of atom
Term
geometric isomer
Definition
same covalent relationships and differ in spatial relationships caused by double bonds
Term
enantiomer
Definition
are mirror images caused by having a carbon bonded to four different things; asymmetrical carbon
Term
asymmetric carbon
Definition
the middle carbon in an enantiomer that is attached to four different atoms
Term
functional group
Definition
groups of elements commonly attached to C that are involved in chemical reactions; determine behavior of molecule
Term
hydroxyl group
Definition
a hyrdogen is bonded to an oxygen, which is then bonded to the carbon skeleton; is polar and dissolves in water
Term
alcohol
Definition
organic compounds containing hydroxyl groups
Term
carbonyl group
Definition
consists of a carbon atom joined to an oxygen atom by a double bond; acts as an acid
Term
aldehyde
Definition
organic compound where the carbonyl group is on the end of a carbon skeleton
Term
ketone
Definition
organic compound where the carbonyl group is located somewhere other than the end of a carbon skeleton; at least three carbons long
Term
carboxyl group
Definition
where an oxygen atom is double-bonded to a carbon atom that is also bonded to a hydroxyl group
Term
carboxylic acid
Definition
compounds containing carboxyl groups; organic acids
Term
amino group
Definition
consists of a nitrogen atom bonded to two hydrogen atoms and to the carbon skeleton
Term
amine
Definition
an organic compound in the amino group
Term
sulfhydryl
Definition
consists of a sulfur atom bonded to an atom of hydrogen, resembling a hydroxyl group in shape
Term
thiol
Definition
organic compounds containing sulfhydryls
Term
phosphate group
Definition
contain a phosphate ion covalently attached by one of its oxygen atoms to the carbon skeleton; transwers energy between organic molecules
