With the molecule for caffeine if possible.
I
am not sure what you mean. I am suppose to show an addition
reaction like hydrogenation, halogenation or hydration with a
molecule of my own choosing. i have to draw the starting material
and then add a reaction and draw the product of the reaction. Then
answer the 3 questions.

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...

Q 10 - Synthesis question. Show how the starting material can be converted to the product through any of the reactions you have learned in Ochem-l and Ochem-Il. Show all the reagents you need and indicate the stereochemistry when appropriate. You do not need to show arrow pushing like in a mechanism question, only the reactions. If a chiral molecule is formed mark the chiral center with an asterisk (*) and write "racemic" below the structure. All carbon atoms in...

c. this is asking for the product of the last step
Draw the structure(s) of the major organic product(s) obtained after workup of the following reaction. HN- S-NH2 + 1 eq. HBr Sulfanilamide "sulfa" antibacterial • You do not have to consider stereochemistry. • If no reaction occurs, draw the organic starting material. • Include counter-ions, e.g., Na+, I', in your submission, but draw them in their own separate sketcher. • Draw one structure per sketcher. Add additional...

Here is a molecule. Do a retro synthesis (reaction
scheme) on the molecule and go all the way back to produce the
molecule until you can't go back anymore (think benzene or carbon).
You can use any source and synthesis/reaction to produce the
molecule above. Some notes about the molecule:
I would say start by writing down all the one step
reactions you know that would make the molecule without considering
from where the starting material comes. With some luck...

1. A Robinson annulation is a reaction that involves: (i) a Michael addition of an enolate onto an ,ß-unsaturated enone followed by (ii) an intramolecular aldol reaction. The molecule shown below (cyclohexenone X) can be made through two different Robinson annulation reactions. (A) Show the two different sets of starting materials (i.e. ketone 1 &a,p-unsaturated enone 1 and ketone 2 & a,B-unsaturated enone 2) for each Robinson annulation. Draw the reagents/reaction conditions. (B) Then pick one set and draw an...

4. (15 Points) Pericyclic Reactions: The transformation below can be described as a pericyclic reaction followed by a polar-acidic mechanism, where the acid is not shown because it is picked up from the environment. (a) Start by redrawing the starting material below, and show how the pericyclic reaction occurs with curved arrows. (b) Specify the type of pericyclic reaction it represents and the name reaction. (c) If you've done the pericyclic reaction correctly, your product will be an enol. From...
