- Draw an alkyl halide that would undergo SN2 reaction to yield this product under the conditions shown below.arrow_forwardComplete the following reactions by providing the missing product(s). Determine what mechanism operates in each case (SN1, SN2, E1, or E2). Show the stereochemistry of the product(s) where appropriate. If more than one product is formed circle the major one.arrow_forwardDraw the major product of the following sequence of reactions. If the reaction is likely to give you a mixture of ortho and para disubstituted compounds you should assume that they can be separated; continue the synthesis with either one. If so, draw the intermediates as well. CH3 K₂Cr₂07 Cl₂, AlCl3 H2SO4arrow_forward
- Draw an alkyl halide that would undergo an SN2 reaction to yield this product under the conditions shown below. Use wedge and dash bonds to indicate stereochemistry where appropriate. Draw Starting Alkyl Halide CH3OK THEarrow_forwardDraw the structure for the alkyl bromide that will produce the alkene shown as the only product of an E2 reaction.arrow_forwardDraw an alkyl halide and choose the best reaction conditions that would undergo an SN2 reaction to yield this product shown below.arrow_forward
- Propose a multi-step synthesis of the target molecule shown at the right, using the starting materials on the left and any other reagents you need. Show the reagents needed for each step and the product of each step. You will need 4 reaction arrows. Remember: Aldehyde + terminal alkyne anion in acid = alcoholarrow_forwardOccasionally, a chemist might need to invert the stereochemistry of an alkene—that is, to convert a cis alkene to a trans alkene, or vice versa. There is no one-step method for doing an alkene inversion, but the transformation can be carried out by combining several reactions in the proper sequence. How would you carry out the following reactions?arrow_forward4) One of the diastereomeric cyclohexyl bromide starting materials below will readily undergo an E2 reaction while the other one will not. Fill in the requested information in boxes and lines indicated including the structure of the alkene product that does undergo an E2 reaction (use scratch paper first please). draw the expected major alkene product draw lowest E chair conformations Me. Ме Me EtO: Na Me "Ме :Br: Ме. Ме Me Me" Ме EtO: Na :Br: Required arrangement of H and LG (Br) for E2? (no acronyms). What is the rate law for and E2? On the template at left, draw all o & o* orbitals involved in the allowed E2 process.arrow_forward
- Give two possible [1,2]-rearrangement products where an alkyl group migrates in the following compound. Motivate also which of the two products will be formed preferentiallyarrow_forwardIn an E2 mediated elimination reaction of an alkyl halide (H-X) using NaOCH3 as base, which of the following statement is not true? O The reactivity order for alkyl halides (RX) is tertiary secondary> primary. O The rate of reaction = k2 (alkyl halide] [NaOCH₂] O The reaction occurs in a single step. O The rate is independent of the leaving group.arrow_forwardDraw the starting alkyne that would lead to the following two products under these conditions.arrow_forward
