okay what is the displayed structural formula of poly(butene) ?

@d!_†oX!©:
hey really sorry ari...just forgot about it yesterday
so yeah...i saw the question...so basically...the diagram that u have made on the last page are correct...both are correct as they are isomers so both will be accepted for sure.....
ur second question....poly(butene)
its simple u just take butene....nd remove the double bond...here is a daigram
    H    H   H
    |     |   |
H-C-C=C-C-H     this is butene
   |  |      |
   H H      H

now rearrange this to move the last methyl group (CH3) below and transfer one of the double bonds to the right to make it a continuous chain

       H        H
       |        |
(-H- C -C - C -)n    this is poly(butene)
       |  |     |  
      H  H  H-C-H
                 |
                 H
or this can be simply written as

(-CH3-CH2CH-)n
               |
              CH3
                                          
                                          

holtadit:
So is this correct too ? Would an IGCSE examiner except it ?

If it is WRONG then explain to me how u got the CH3 for poly(propene) and how i should be drawing the repeat units for polymers.

Ghost Of Highbury:
propene is

ok look at the diagram

the first when the first CH2 is put from ; remains

next one has a C with  a H bond on top and methyl at the bottom

When the C and H bond is drawn from remains only because 1 C and 1 H is gone..



to form a polymer just remove the double bond and extend the lines outside
