Term
functional group
Definition
an atom or group of atoms that is responsible for the specific properties of an organic compound
Term
alcohols
Definition
organic compounds that contain one or more hydroxyl groups
Term
alkyl halides
Definition
organic compounds in which one or more halogen atoms-flourine, chlorine, bromine, or iodine are substitued for one or more hydrogen atoms in a hydrocarbon
Term
ethers
Definition
organic compounds in which two hydrocarbon groups are bonded to the same atom of oxygen
Term
aldehydes
Definition
organic compounds in which the carbonyl group is attached to a carbon atom at the end of a carbon-atom chain
Term
ketones
Definition
organic compounds in which the carbonyl group is attached to acarbon atoms within the chain
Term
carboxylic acids
Definition
organic compounds that contain the carboxyl functional group
Term
esters
Definition
organic compounds with carboxylic acid groups in which the hydrogen of the hydroxyl group has been replaced by an alkyl group
Term
amines
Definition
organic compounds that can be considered to be derivatives of ammonia
Term
primary amine
Definition
one hydrogen atom of an ammonia molecule has been replaced by an alkyl group
Term
secondary amine
Definition
two hydrogen atoms of an ammonia molecule have been replaced by alkyl groups
Term
tertiary amine
Definition
all three hydrogen atoms of an ammonia molecule have been replaced by alkyl groups
Term
substitution reaction
Definition
one in which one or more atoms replace another atom or group of atoms in a molecule
Term
addition reaction
Definition
one in which an atom or molecule is added to an unsaturated moelcule and increases the saturation of the molecule
Term
condensation reaction
Definition
one in which two molecules or parts of the same molecule combine
Term
elimination reaction
Definition
one in which a simple molecule such as water or ammonia is removed from adjacent carbon atoms of a larger molecule
Term
polymers
Definition
large molecules made of many small units joined to each other through organic reactions
Term
monomers
Definition
the small units
Term
copolymer
Definition
a polymer made from two or more different monomers
Term
thermoplastic polymer
Definition
melts when heated and can be reshaped many times
Term
thermosetting polymer
Definition
does not melt when heated but keeps its original shape
Term
addition polymer
Definition
a polymer formed by chain addition reactions between monomers that contain a double bond
Term
vulcanization
Definition
a cross-linking process between adjacent polyisoprene molecules that occurs when the molecules are heated with sulfur atoms
Term
condensation polymer
Definition
a polymer formed by condensation reactions
