- Given that an E2 reaction proceeds with anti periplanar stereochemistry, draw the products of each elimination. The alkyl halides in (a) and (b) are diastereomers of each other. How are the products of these two reactions related? Recall from Section 3.2A that C6H5 −is a phenyl group, a benzene ring bonded to another group.arrow_forwardGiven that an E2 reaction proceeds with anti periplanar stereochemistry, draw the products of each elimination.

- Need help with part c. The cyclohexane derivative shown below does not undergo E2 elimination. what do we do after we roate the bond roate the bond.arrow_forward1. Which of the following is the strongest nucleophile? Refer to the diagram below with an MeOH, MeSH, etc. 2. Which of the following is true about the stereochemistry of SN1 reaction?a.retention of configuration at the electrophilic centerb.50:50 mixture of retention and inversion of configuration at the electrophilic centerc.inversion of configuration at the electrophilic centerd. slightly more inversion than retention at the electrophilic centerarrow_forwardProvide the mechansim using curved arrows of the reaction of p-t-butyl phenol treated with acetic anhydride in AlCl3. Include resonance stabilized intermediates and if more than one product is formed, label them as major, minor, etc. thank you for the helparrow_forward
- 20. (a) Show all steps in the synthesis of 2-pentene from 2-bromopentane. Show the structure of all reactants and product. CH3CHBrCH2CH2CH3 -------> CH3CH=CHCH2CH3 (b) Correctly identify the mechanism in (a) above(SN2, SN1, E2, E1)arrow_forwardWhich organo-chloride below is most reactive in SN1 reactions?arrow_forwardWhich is the better retrosynthesis for the given target molecule? Explain, and provide a one-step synthesis of the target molecule. A A is the better starting material because B can form both E and Z alkenes. B A is the better starting material because it will produce only the desired target molecule. C B is the better starting material because only B has β protons in the trans position. D B is the better starting material because A can form both E and Z alkenes. E B is the better starting material because it will produce only the desired target molecule. F A is the better starting material because only A has β protons in the trans position.arrow_forward
- a. Explain why 1-bromo-2,2-dimethylpropane has difficulty undergoing both SN2 and SN1 reactions. b. Can it undergo E2 and E1 reactions?arrow_forwardWhich isomer reacts more rapidly in an E2 reaction: cis-1-bromo-4-tert-butylcyclohexane or trans-1bromo-4-tert-butylcyclohexane? Explain your answer.arrow_forwardWhy is the alkyl bromide substrate below not capable of undergoing an E2 elimination reaction upon treatment with potassium hydroxide (KOH) in ethanol (EtOH)? -Br– is too poor a leaving group. -Too much angle strain would be present in the alkene product. -Potassium hydroxide is a poor base to use in E2 reactions. -An anti-periplanar E2 elimination cannot occur due to the lack of a beta-hydrogen in the substratearrow_forward
