C11: Polymers Flashcards
(14 cards)
What are plastics made from
Very large covalently bonded molecules called polymers
How are large polymer molecules made
When many monomers join together
What is addition polymerisation
The reaction between alkene monomers to form a polymer
In condensation polymerisation, what is released when the polymer forms
A small molecule is released
How are polyesters formed
From the condensation polymerisation of a diol and a carboxylic acid
What is given off when polyesters are formed
H20
If a wizard is never late nor is he early, when does he arrive
He arrives precisely when he means to
When simple carbohydrates polymerise, what happens
Polymers such as starch and cellulose are produced
What are proteins
Polymers made from different amino acids
What do amino acids have in the same molecule
Have an acidic and a basic functional group
What happens when amino acids react together during condensation polymerisation
They make polypeptides and proteins made of long sequences of different monomers
What is DNA made up of
Monomers called nucleotides
What are DNA nucleotides based on
They are based on the sugar deoxyribose, bonded to a phosphate group and a base
What does DNA consist of
2 polymer strands intertwined into a double helix
