1. The problem statement, all variables and given/known data In a Diels-Alder reaction with maleic anhydride, which isomer of 2,4-hexadiene would react fastest and slowest: (Z,Z), (Z,E), or (E,E)? Briefly explain. 2. Relevant equations N/A 3. The attempt at a solution I am guessing that (Z,Z) reacts fastest and (E,E) reacts slowest, due to steric hinderence. Is my answer correct? If so, is my brief explanation manageable? Thanks.
