Figures summarize the specific resources activated when the multiple-choice items were provided. Three themes provided insight into how scaffolding assignments could be designed in future iterations. productively applied these resources to identify the correct RCD. Likewise, a similar response was observed for P7 (Markovnikov Addition): I just remembered that I think HBr addition to an alkene is not a concerted reaction that has a carbocation intermediate… So because the difference between the minor and major product would be in the cation formation step and the more stable carbocation would be the lower energy. Although most prevalent with the 530 Markovnikov addition, similar observations were noted for the Zaitsev elimination. When provided with the four options, P5 (Zaitsev Elimination): "Okay, um, so I guess it was E2." The RCDs were concerted, which allowed P5 to rule out the E1 as a possible mechanism.
