Tertiary (3°) alkyl halides react faster than 2° or 1° alkyl halides.Assignment 4 - Energy Diagram Illustrating Your Experience of Snowmaggedon The instructions are simple, draw an energy diagram (or reaction coordinate diagram) that illustrates your experience during our snowmaggedon (think Sn1/Sn2/E1/E2 reaction coordinate diagram). The diagram is to illustrate your "reaction" progress of your experience as you navigated this week. Add as many transition states and intermediates that you see fit (be sure to give detail of each hill and valley). For example: What was the highest, lowest, moderate transition state during your reaction and why? Was your experience exothermic or endothermic? (draw accordingly (-))
