“Catalyst” “The hydration of sucrose into glucose and fructose is catalyzed by acid. The addition of HCl makes the reaction sufficiently fast for us to measure its rate constant. Now imagine doing this experiment without the addition of HCl: how will this change the activation energy, Ea, of the reaction?

3. Draw a stepwise, detailed mechanism for the acid-catalyzed hydration reaction in question 2 above. Use curved arrows to indicate the flow of electrons. (Note: use hydronium ion, H307, in your mechanism to indicate "acidic water"). (6 pts) 4. Draw a stepwise, detailed mechanism for the reaction below. Use curved arrows to indicate the flow of electrons. (Hint: think of this reaction as a combination of addition of HX (step 1) and hydration (step 2)]. In the second step, an...

How to properly solve these elimination and addition
reactions
Elimination and Addition reactions Purpose: Figuring out the ways that molecules react is the province of the mechanistic chemist. By understanding the mechanisms of reactions, the chemist can manipulate the experimental variables to favor one product over another. This element of control is the province of the synthetic organic chemist. This Workshop continues to explore how we know how molecules react and how this knowledge leads to control of the products....
