Question 4
(6 marks)
Excess propane and propene gases are bubbled into bromine water (Br2(aq)) in two separate
containers. Both reactions are carried out under the same conditions at room temperature in the
presence of UV light.
Complete the following table describing these reactions.
Propane
Would you expect the reaction
to be fast or slow?
Draw the structure of any
possible organic products
formed.
State the name of this type of
reaction.

Propene
Question 5
(8 marks)
Consider the following straight (unbranched) chain alkene, cis-pent-2-ene.
cis-pent-2-ene.
trans-pent-2-ene.
(a) Complete the table above.
(1 mark)
(b) Draw a condensed (showing no bonds) structural formula and write the name of the product
formed when cis-pent-2-ene reacts with bromine water, Br2(aq).
(3 marks)
(c) Victor mixed bromine water with cyclohexane. There was no observable change. Explain this
observation.
(2 marks)
(d) cis-pent-2-ene is an alkene, cyclopentane is a cycloalkane. Explain, using a diagram as
required, why benzene (C6H6) is neither an alkane nor a cycloalkene.
