Chapter 14 Flashcards
hydrocarbons
composed of hydrogen and carbon
unsaturated
molecules that have double and triple covalent bonds
saturated
all bonds are single ones and no new atoms may be joined without the removal of others that are already bonded
isomerism
hydrocarbon compounds with the same composition may have different atomic arrangements
macromolecules
gigantic in comparison to the hydrocarbon molecules
repeat units
long molecules that are successively repeated along the chain
monomer
small molecule from which a polymer is synthesized
polymer
many units
homopolymer
when all of the repeating units along a chain are of the same type
copolymers
chains composed of two or more different repeat units
bifunctional
monomers that have an active bond that may react to form two covalent bonds with other monomers forming a two-dimensional chainlike molecular structure
functionality
number of bonds that a given monomer can form
trifunctional
three active bonds, from which a three-dimensional molecular network structure results
linear polymers
those in which the repeat units are joined together end to end in single chains
branched polymers
polymers synthesized in which side-branch chains are connected to the main ones
