5 (a) The hydrocarbon M has the structure shown below.
CH3CH2-C=CH2
|
CH3

i) Name the hydrocarbon M

ii) Draw the repeating unit of the polymer which can be formed from M.
State the type of polymerisation occuring in this reaction
[Please attempt to the best of your ability]

iii) The reaction between M and benzene in the presence of HCl and AlCl3 is similar
to the reaction between ethene and benzene under the same conditions.
Name the type of mechanism involved and draw the structure of the major
product formed in the reaction between M and benzene

iv) Draw a structural isomer of M which shows the geometrical isomerism

i may be a bit rusty!

1)

2-methylbut-1-ene

2)
this will be quite hard doing it on here lol

C----CH2 (---)
I
CH3

sorry you'll have to do w/out can't type it !


Type: radical

3) name of mechanism

electrophilic subsitution


CH3

CH3


they are too hard to draw out on here sorry

i) 2-methylbut-1-ene

ii) see attachment. addition polymerisation.

iii) electrophilic substitution. see attachment. the non-phenyl part of the molecule may be the other way round (horizontally), i'm not entirely sure.

iv) see attachment.
