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

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
                                          
                                          
AAL IZZ WELL!!! ;)

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.

propene is C_3H_6

ok look at the diagram

the first when the first CH2 is put from C_3H_6 ; C_2H_4 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 C_2H_4 remains only CH_3 because 1 C and 1 H is gone..



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

Ill check the song out.

But is my diagram of poly(butene) correct ? because i followed the same method that A@di just explained.

yes ari , that shud be correct..

but lemme suggest u something

always...a methyl group i.e CH_3 is better to show in a polymer than an ethyl i.e C_2H_5 or any other alkyl

for that just make one more CH2 and insttad of an ethyl hanging make it to a methyl

i agree with aadi....try to put methyl group....a better idea.more widely accepted...

Point noted. Sorry for asking so many questions guys and thanks for helping me out. But i have one last question:

Is this the correct diagram for the following question?


The synthetic polymer, nylon, has the same linkage as proteins. Draw the structural
formula of nylon.

Why does nid404 say that the double bonds break open ???
