C1d - Making polymers

Question 1

What is a hydrocarbon

Answer 1

compound whose molecules contain hydrogen and carbon atoms only

Question 2

What is a saturated compound

Answer 2

compound that contains only single covalent bonds between carbon atoms

Question 3

What is a unsaturated compound

Answer 3

compound that contains at least one double bond between carbon atoms

Question 4

What are alkane + general formula

Answer 4

saturated hydrocarbon whose atoms are bonded via single covalent bonds only

CnH2n+2

Question 5

What are alkene + general formula

Answer 5

unsaturated hydrocarbon that contains a double covalent bond between 2 of its carbon

CnH2n

Question 6

What are double bonds

Answer 6

2 shared pairs of electrons between atoms

Question 7

How can you test for alkenes

Answer 7

bromine water turns from orange to colourless in the presence of an alkene

Question 8

Explain the reaction between an alkene and bromine water (2)

Answer 8

addition reaction takes place between bromine and alkene

-forms a colourless dibromo compound

Question 9

Describe addition polymerisation (3)

Answer 9

a process in which many unsaturated alkene monomer molecules react together to form saturated a polymer which only contain single covalent bonds

The reaction causes the double bond in the monomer to break and each of the two carbon atoms to form a new bond

Requires high pressure and catalyst

Question 10

Try drawing displayed formulas of polymers and monomers(no answer)
