- Which of A to E shows the structure of the major product obtained from the E1 reaction shown below?1. Draw a reasonable arrow-pushing mechanism for the transformation shown along. 2. Identify nucleophiles and electrophiles 3. Name any type of reactions taking place like E2 or E1 4. Account for any regio- or stereoselectivityNeed 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.
- Which compounds from 5a-d will react with hydroxide in the fashion shown. Which reaction will be the fastest and slowest? Explain using knowledge of carbonyl chemistry, pka and leaving groups.Why we need step 3 before step 4? a. Because the nitro group increases the electrophilicity at the ortho positions which is where the bromine is added. b. Because the amine group is a strong ortho, para director which is what controls the regiochemical outcome of this bromination. c. Step 4 is unessesary. The symmetry of compound 3 allows for the bromination to be regioselective and give compound 5. 5. There will be a mixture of products because there is no selectivity for a major product.After E2 elimination, will this product contain deuterium (D)? Justify your answer.

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 centera. What are the products of following reactions?b. Write the reaction mechanism for each using the right arrows and define it as Sn2, Sn1, E2 or E1.c. Explain why do you choose that product and mechanism or in case something else happens explain why.Substitutions vs elimination. Pls help me identify the major products and the dominant mechanism.
