Glucose, organic chem., HELP !!

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

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

lol..actually i want to dedicate that song to my friend ari...

@ari - listen to this song -> bombay rockers - ari ari ari

i'm not kiddin , it is a song..check it..no offence

@ari - listen to this song -> bombay rockers - ari ari ari

i'm not kiddin , it is a song..check it..no offence 

Ill check the song out.

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

its a coooooool song...really like it....specially the remixed one with overseas!!!awesome

[Ghost Of Highbury]

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 is better to show in a polymer than an ethyl i.e or any other alkyl

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

[@d!_†oX!©]

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

[holtadit]

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

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.

ends split open...the double bond opens....m havin my food nw...will draw and reply asap

[@d!_†oX!©]

yah its correct ari!!!!
just put a dash(-) on the 2 brackets on the side to show continuation....

[holtadit]

Why does nid404 say that the double bonds break open
