a. Caffeine can be protonated under acidic conditions to form an imidazolium-like species. Draw the structure for this protonated form, then find and report a pKa value for the most acidic proton. b. Draw a reaction scheme between caffeine and water. Which side of the equilibrium is favored for this acid/base reaction? Hint: Use the pKa value from part a....

2-Chloropropane Based on what you have learned so far, predict the more stable product in the reaction of CH2=CH-CH2-CH3 with HBr (circle the arrow for the step that leads to the predicted product), then calculate the energies of intermediates and products. Reactions normally go through the most stable intermediate, irrespective of the stability of the product. Circle the product you...

answer all questions
1. For the following substrates, predict whether a carbocation rearrangement will take place in an SN1/E1 mechanism by first drawing the carbocation intermediate, then deciding if the carbocation will rearrange (can it form a more stable carbocation by hydride or methyl shift?): Carbocation: Sturcture Rearrange? If yes, draw the rearranged product. If no, write No н.с Br...

Tutored Practice Problem 16.4.1 COUNTS TOWARDS GRADE Predict and calculate the effect of concentration changes on an equilibrium system. Close Problem Some COCl2 is allowed to dissociate into CO and Cl2 at 873 K. At equilibrium, [COCI2] =0.237 M, and [CO] - [C12] = 0.128 M. Additional CO is added so that (CO)new = 0.193 M and the system is...

19. (Extra credit: 4 pts each) Predict the major expected product or products of each reaction or reactions shown below. It is recommended that you show your reasoning, such as intermediate compounds produced in any multi-step sets of reactions for partial credit. If stereochemistry at any site is important, be sure to show it clearly. Partial...
