Answer all parts of the question please. ง 6) The compound provided below was found to occur via an SN1 mechanism in the presence of a strong nucleophile NASH which have a high electron density. You are required to justify this mechanistic approach based on several potential stabilizing factors in the structure. You are to clearly show hybridization orbitals, electron-pushing arrows to signify any stabilizing factor. Add lone pairs when applicable.

3. What type of bond cleavage (homolytic or heterolytic) would you expect the following bonds to undergo? Write the bond cleavage process using the curved arrow convention for each.   Show the step-by-step process. Do not use shortcut methods. Make it as detailed as it can be. Encode (not hand-written)!

Complete the mechanism of hydration of alkene below. Please follow curved arrows to predict the resultingstructures in each step.

This structure has a lower pKa than usual because the conjugate base of the structure has unusual stability. Using the provided resonance structures, draw the curved electron-pushing arrows to show the deprotonation step. Then, draw the curved electron-pushing arrows to show the interconversion between resonance hybrid contributors. Be sure to account for all bond-breaking and bond-making steps

Please answer part b and c

3. An alkene can be converted into an ether in the three mechanistic steps shown below. Complete this mechanism by: Draw curved arrows to indicate the flow of electrons for each step. Lone pairs are omitted for clarity but be sure to include lone pairs on atoms that are involved in bond formation/breaking. Draw the reaction intermediates in the appropriate boxes. Include all nonzero formal charges. Classify each step of the mechanism using the boxes below each arrow as one of the following: acid- base proton transfer (AB), nucleophilic attack (NA), elimination (E), or rearrangement (R). + H-OMe H-OO + MeOH + MeOH + H-OMe H-OO 48

2) Provide a detailed mechanism for the addition reaction shown below. State the regiochemistry and explain why it's unusual. SCH3 HBr Br SCH3 EN Please be sure to include all structures (use line angle notation or perspective diagrams as appropriate to illustrate the stereochemistry of the process), resonance forms, intermediates, transition states, curved arrows, formal charges, or lone pairs as necessary. Please redraw the substrate

10. Help

Rationalize the formation of compound B using the arrow-pushing formalism. Draw all missing reactants and/or products in the appropriate boxes by placing atoms on the canvas and connecting them with bonds. Add charges where needed. Electron-flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created.
