Polymer Question

  1. Mar 16, 2009 #1
    1. The problem statement, all variables and given/known data

    Draw the structural formula for a three-monomer segment of poly(1,3-butadiene) in which addition is 1,2 for the middle unit and 1,4 for the outer units, with double bonds Z.

    2. Relevant equations

    Markovnikov's rule: H goes to the Carbon with the most H's

    3. The attempt at a solution

    Not too sure on this one.

    1,3 butadiene is CH2=CH-CH=CH2

    My attempt is posted in the picture

    I know how to make it E or Z its just I do not know where the chains become bonded and how.

    1,2 was for the MIDDLE unit, not the leftmost one.
