(2) In radical chlorination, the key propagation step is hydrogen abstraction. This is exothermic because chlorination forms a strong H-Cl bond (103 kcal/mol). According to the Hammond Postulate, the reaction profile and transition state would be predicted to look like

A) I
B) II
C) III
D) IV

Transcribed Image Text:The image consists of four reaction profile diagrams, each illustrating a chemical reaction involving R3C, H, and Cl. The x-axis in all diagrams is labeled "Reaction Profile Diagram," and the y-axis is labeled "Energy." I) The first diagram shows a typical energy curve with a single peak, indicating a transition state. The notation is R3C—H––Cl, suggesting an interaction between the chemical species. II) The second diagram also displays an energy profile with a peak. The curve rises, reaches a transition state, and then falls back, depicting the energy changes during the reaction. The interacting species are again denoted as R3C—H––Cl. III) The third diagram has a similar shape to the first, with a peak indicating the transition state. The energy changes follow the pattern R3C—H––Cl. IV) The fourth diagram shows an energy profile with a peak that is slightly skewed compared to the others, representing a different energy transformation. The species involved are labeled as R3C—H––Cl. Each diagram visualizes the energy changes during the reaction process, highlighting transition states where the highest energy exists.
