CHEM 2602 Exam 2 March 25, 2020 For questions 5 and 6 Show the major product for each of the reactions, paying attention to stereo and regiochemistry where necessary. Draw the mechanism (show all relevant lone pairs, formal charges, curved arrows, etc.) for ONE of the reactions your choice, circle the letter for the mechanism you want me to grade) NaOH
4. Add curved arrows to show the movement of electrons in each of the following reactions. Note that you should draw in any lone pairs that are relevant to the mechanism. (a) OCH2 CH3 -O. H + (b) CH3 IN OH CH2 + +
2. Provide the complete mechanism (curved arrows) to show how the product is formed. Include all lone pairs, formal charges, curved arrows, intermediates, and products. You do not need to draw the structures of transition states. If there is a carbocation rearrangement and/or a proton transfer, be sure to include it (them) in your mechanism. (Remember to start by drawing all ionic compounds as ions/drawing out the structure of all reagents, and drawing in all lone pairs.) HCI 3. Which...

1) Draw a rational mechanism for the reaction shown below. Use curved arrows appropriately. Show all relevant intermediate(s) and lone pairs of electrons and formal charges where appropriate. HO H2SO4 Ome
Write a reaction mechanism to show how the major mononitrated product forms when protonated methyl benzoate (a nucleophile) combines with nitronium ion (an electrophile). Use the curved-arrow formalism. Show all lone pairs and formal charges.
Write the complete stepwise mechanism for the
acid catalyzed hydrolysis of the compound shown. Show all
intermediates, indicate with curved arrows the movement of
electrons and show all formal charges and lone pairs of electrons
where relevant. Will rate and comment, thank you in
advance!
3. Draw the important resonance contributors for each structure below (Hint - only 3-4 required for each). Include resonance arrows as necessary, and use the curved arrows to show electron movement. Also be sure to show all relevant lone pairs and formal charges. :0: H3CNCH CH3
9. a) Write the detailed Sn1 mechanism for the reaction of (S)-3-bromo-3-methylhexane with H20, showing curved arrows, relevant lone pairs, formal charges, stereochemistry for each step. Include any transition states and/or intermediates, and name the product(s). b) A racemic mixture results from a reaction of the chiral alkylbromide starting material below, and acetate. at hope ܬ Write the complete mechanism for the synthesis. Show the curly arrows, relevant lone pairs and all formal charges for each step. Include any transition...
