Epoxides are highly strained and can alleviate the strain by reacting under acidic and basic conditions to give different regiochemical and stereochemical products. In this epoxide tutorial, we will cover 1. ring opening of unsubstituted epoxide 2. which nucleophiles will open an epoxide 3. regiochemical and stereochemical results of basic ring opening of asymmetrical epoxides 4. regiochemical and stereochemical results of acidic ring opening Step 3: If the nucleophilic attack takes place on a chiral epoxide, an inversion of configuration is observed. Consider the epoxide ring-opening of a chiral epoxide. 1. NaSH ? 2. H₂O Select the product or products of the reaction. SH SH SH JOH ...OH OH OH .....SH

For which reaction mechanisms—SN1, SN2, E1, or E2—of thefollowing statement true? A statement may be true for one or moremechanisms. The reaction rate increases with better leaving groups.
Rank the attached dienophiles in order of increasing reactivity.
A. For each reaction1) Provide the missing reagents/conditions or major organic products as appropriate2) Assign each reaction as Oxidation or Reduction unless otherwise directed3) Pay attention to stereochemistry including racemic mixtures unless specified
Does dehydrogenation of alkyl halides create Zaitsef or Hoffman products? In this example, which is created? I think it's Hoffman because there is a more stable/substituted option which is to put the double bond to the right of the positive charge instead of to the left. Or does it depend on the reactants? Further clarification is needed. Thank you in advance!
Draw the (pericyclic) reaction (reaction 1), including all mechanistic steps, that lead from the starting materials to the intermediate product. Show all isomers that can be formed and provide an explanation as to why that is. Determine the configuration of all chiral centers. I included the molecule, the retrosynthesis of the molecule, and reaction 1 to help solve this question.
For each section, circle the mechanism from the two options given (SN1 or SN2) and draw the main organic product resulting from that mechanism. Indicate the stereochemistry and if two configurational isomers form, draw both.
An SN2 mechanism's top requirement from an aprotic solvent is to ensure that it can stabilize the leaving group.
Draw the major organic products obtained from the reactions below. Be mindful of stereochemistry and regioselectivity. If stereochemistry is included in the product, note that the diast/enant is also included, but not provided due to space. Assume one equivalent unless stated otherwise, or if the reagent is a solvent, oxidant or reductant.

According to the LUMO density map, on which face is the LUMO electronically more exposed to nucleophiles? Based on this data, which face would be more electronically favored? (These questions go hand in hand.)
For the following synthetic scheme, draw the structure of the product of each reaction. Ignore stereochemistry for all structures.
