The reactants, intermediates, final products, and all curved arrows showing bonds forming andbreaking are collectively referred to as the mechanism of a reaction. For the following reactants: a. Explain why the original statement of Markovnikov’s rule does not help in this case, but themodern restatement of Markovnikov’s rule tells you which carbon will get the X (Cl). b. Show the mechanism of the most likely addition reaction between the reactants.
5. Relative Rates and Stereochemistry ( (a) For the following sets of substitution reactions, draw the major organic product(s) with the stereochemistry indicated, and indicate which reaction occurs at the faster rate. If two configurational isomers form in similar amounts, draw both. (i) Substitution via SN2 mechanism (same expected product(s) for both, can draw once) CH3O CH3O H3C. CH3 CH3 CH3O H3C. CH3 (ii) Substitution via SN1 mechanism H3CO H3C. CH3OH H3C H3C H CH3OH
Show SN1 and SN 2 Mechanisms on paper please
The substitution of an Iby a Clon H3C-I can occur by two possiblemechanisms:Mechanism I: step 1. H3CI → H3C+ + I- slow stepstep 2. H3C+ + Cl- → H3CCl fast stepMechanism II: step 1. H3CI + Cl- → H3CClI slow stepstep 2. H3CClI → H3CCl + I- fast stepa.) Write a rate law for each reaction.
79 3. Complete the following reaction and write a mechanism for both the substitution and elimination products (both substitution and elimination products occur simultaneously). Discuss all criteria including stereochemistry when a chiral secondary primary alkyl halide with (S) configuration reacts with methanol a weak nucleophile. Draw energy profile for this reaction. (4 points) CH2CH3 CH₂O-Na+ + Br H3C (S) no 1999b 02.907 90 +20110
Predict the product.
While we are at it, let's do the same thing for the second step of the mechanism. Again, what is happening with the arrows circled in red below? Cys157 Cys157 Cys157 His296 His296 His296 OH OH HN, HN HN -CO2 CH2 Asn329 Asn329 Asn329- Cys157 His296 OH OH HNNH HyC. H,C. Asn329- O deprotonation of the conjugate acid form of imidazole, followed by general base assistance in decarboxylation O nucleophilic addition of the cysteine side chain to imidazole O decarboxylation coupled with the generation of molecular hydrogen (H2) O general acid catalyzed isomerization n covalent attachment of the substrate to the enzyme
13. (11pts total) Consider the arrows pointing at three different carbon-carbon bonds in the molecule depicted below. Bond B Bond A Bond C a. (2pts) Which bond between A-C is weakest? Which is strongest? Place answers in appropriate boxes. Weakest Bond Strongest Bond b. (4pts) Consider the relative stability of all cleavage products that form when bonds A, B, AND C are homolytically cleaved/broken. Hint: cleavage products of bonds A, B, and C are all carbon radicals. i. Which ONE cleavage product is the most stable? A condensed or bond line representation is fine. ii. Which ONE cleavage product is the least stable? A condensed or bond line representation is fine. c. (5pts) Use principles discussed in lecture, supported by relevant structures, to succinctly explain the why your part b (i) radical is more stable than your part b(ii) radical. Written explanation can be no more than one-two succinct sentence(s)! Google
please help with part A,B,C,D:
Please show the mechanism with arrow formalism.
