C11 Polymers Flashcards
what is plastic made of
large covalantly bonded molecules called polymers
examples of polymers + qualities
poly(ethene) is a really sueful plastic as it is strong and easy to shape, and transparent
poly(propene) forms a strong tough plastic
how are large polymers created
by joining many monomers
what do all monomers contain in addition polymerisation
C=C bond
name of the reaction between alkene monomers to form a polymer
addition polymerisation
what happen when two alkanes molecules are joined
the double covalent bond between the two carbons is raplaced by a single covalent bond.
in polymers the repeating unit as the same atoms as the…
monomers, because when the double bond of carbon opens up no other molecule is formed in the reaction
what does condensation polymerisation include
small molecule is released in the reaction,as the polymers forms
usually what monomers are used to make the simplest condensation polymers, what has to happen for the chains to be formed.
2 different monomers with different functional groups. it is important that the functional group on the 2 different monomers must react together
when are polyesters formed
from condensation polymerisation of an diol(an alcohol) and dicarboxylic acid , water given off in the reaction
what are carbohydrates made of
compounds made made up of molecules containing C,H,O + types of sugar molecules.
most common sugar and name+ formula
glucose is a monosaccharide with formula C6H12O6, made during photosynthesis.
what can monosaccharides do
can bound together to make larger molecules.
can act as monomers to make polymers.
what do simple carbohydrates polymerise make
polymers such as starch and cellulose
glucoso monomers are joined in condensation polymerisation.
glucose monomers =starch polymers+water
glucose monomers=cellulose polymers + water
what are proteins made from
polymers made from different amino acid monomers
