i need help filling out the following SN2 reactions with appopiate reactants, products, or reagents,
Hi there, can someone please help me solve this problem? Please make sure to clarify all steps taken to go about solving for the products and explain various terms and rules that should be known or correlate with the question. I'm using these questions to study for our final exam and need some extra clarification on rules and steps. Thank you very much in advance!
Can you draw the products that form when 1-butene reacts with; O3, then Me2S OsO4, then NaHSO3/H2O Br2 in H2O Please analyze in detail for each. Also can you please reply fastly?
Minor product via E1 for 2-butanol and HCl?
Good hand written explanation Asap Thanks What is an azeotrope? a) A mixture of compounds that is dangerous to distill. b) Any mixture that cannot be practically separated by distillation c) A set ratio of compounds that can only be distilled in the best equipment under the best conditions. d) A set ratio of two compounds (e.g. 5% ethanol in water) that always distills together at the same time.
Fill in what the structures in the boxes should be. This appears to be SN1 to get to the first box, E2 to get to the second, and electrophilic addition to get the final product. Assuming that that's correct, yes it's great I got that, but I'd like to confirm how the whole thing should look.
Box 31-33 .Unless otherwise directed, show only the major product. For reagent or reactant questions, fill in the missing information.
Phineas and Ferbs, two brothers who enjoy vacations, doing fun things every summer. This summer the brothers and their friends carry out an organic synthesis with an unknown compound (L1) that contains 52% Carbon, 6% Hydrogen and 42% bromine, this compound (L1) is treated with magnesium in ether to obtain L2 , which reacts violently with D2O for 1-methyl cyclohexene with a deuterium atom in the methyl group (L3). The L2 reaction is treated with acetone followed by hydrolysis to give L4. Heating L4 with concentrated sulfuric acid gives L5, which decolors the bromine, obtaining L6. L5 undergoes hydrogenation with excess hydrogen and platinum as a catalyst giving rise to isobutyl cyclohexane. Determine the structures of compounds L1 through L6.

I have this task in organic chemistry (book: Brown's introduction to organic chemisty, global edition). Task 10:42. In (a) I have to tell what the funcion of K2CO3 is in step 1. Is it that CO32- take the hydrogen atom in 1-napthol? Will it then be a SN2 mechanism? In (b) I have to name the amine used in step 2 to form Propanolol. But I can't really find out how to come up with an amine that will make that reaction. Here are two pictures of the task:
