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.
