- Consider this organic reaction: Br Draw the major products of the reaction in the drawing area below. If there won't be any major products, because this reaction won't happen at a significant rate, check the box under the drawing area instead. No Reaction.

- Consider this step in a radical reaction: Br Br: ?arrow_forwardHBr addition to ethylene is exothermic. What does this mean? Options: The rate determining step is the first step. The newly formed bonds are more stable (higher dissociation energy) than those broken in the reactants. The carbocation intermediate is higher energy than the alkene. The reaction is very fast.arrow_forwardC5H8 + 7O2 → 5CO2 + 4H2O type of reactionarrow_forward
- Reaction coordinate diagrams: Two-step diagram. Label the reactant (R), product (P), intermediate (I"), and transition states (TS; and TS2), plus the axis with appropriate units/labels. 1) Break the diagram up into 2 steps. Which one is the slow step? The fast step? 2) Endothermic or exothermic? Suppose a is added to step one. Sketch the effect of this addition on the diagram. You can identify the intermediates and by remembering: Intermediates are and then Catalysts are added to a reaction (like a reactant), and are at the end. Practice: Identify the reactants, products, intermediate(s), and catalyst(s). Put a star next to the rate-determining step.
