unit 1; monomers and polymers

Question 1

what are monomers

Answer 1

Monomers are the smaller units from which larger molecules are made

Question 2

what are polymers

Answer 2

Polymers are molecules made from a large number of monomers joined together in a chain

Question 3

what is a covalent bond

Answer 3

the sharing of two or more electrons between two atoms, Covalent bonds are very stable as high energies are required to break the bonds

Question 4

when does a condensation reaction occur

Answer 4

occurs when monomers combine together by covalent bonds to form polymers (polymerisation) or macromolecules (lipids) and water is removed

Question 5

what is a hydrolysis reaction

Answer 5

In the hydrolysis of polymers, covalent bonds are broken when water is added

Question 6
