Provide a detailed step-wise mechanism for the following reaction. Be sure to show all steps, intermediates, formal changes, and show the movement of electrons with curved arrows. You do not need to show transition states.
When treated with NaOH, the bromide below gives an alkene by the E2 mechanism, by eliminationof the circled atoms: (a) Draw the Newman projection from which elimination takes place. (b) Draw the mechanism. (c) Draw the product with the proper stereochemistry. (d) Assign the proper stereochemical descriptor to the product. (Z, E? Trans,CiS?) (e)What would happen to the stereochemistry of the product if the enantiomer of the starting material were used inthe reaction?
Classify the following reaction as an Sn1, Sn2, E1, E1cB, E2 reaction. Can you show me the leaving group and explain how to find a leaving group? And how to identify the other reactions?
Make a table with the main conditions for each mechanism: E1, E2, SN1, SN2.
Below is a convenient way to form product B from starting material A. The reaction starts when compound A treated with sodium hydride, which is a strong base and removes the proton from the OH group. Draw an arc-arrow mechanism that explains the formation of product B. The reaction takes place in several stage. Draw visible all relevant arc arrows, free electron pairs and formal charges.

List all alkene products for each reaction. Write a mechanism for the formation of each product following E1 or E2 mechanisms as appropriate. Be sure to draw arrows for the mechanism.
According to the rules for reasonable mechanisms, the E1 reaction shown here should undergo a 1,2-hydride shift. However, the same product is produced regardless of whether the rearrangement occurs. Br H20, heat (a) Draw the mechanism that includes that carbocation rearrangement. (b) Draw the mechanism that does not include the rearrangement. (c) Experimentally, how can we use 13C isotope labeling to determine whether the rearrangement occurs? In other words, can a 1ºc atom in the substrate be replaced by a 1°C atom so that the E1 products would depend on whether the rearrangement takes place? (d) How can we use deuterium isotope labeling to determine whether the rearrangement occurs?
