1. Homework Statement

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. Homework 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.
