Practice: Nuclophilic Subsitution
A graduate student performs two reactions in order to make some new ethers. In the first reaction the student mixes 3-chloro-2-methylprop-1-ene and methanol and in the second the student mixes 4-chloro-2-methylbut-1-ene with methanol. The next day the student examines the reaction and finds that one has completely finished and the other is not even 10% complete. Which reaction has completely finished? Why?
Structure determination
A molecule A (CH3)3CH2CH2Br) was treated with aqueous NaOH to form B. Compound B was treated with H2SO4 and heated to form C. Product C was reacted with Bromine under dry conditions to yield D. Product D has four possible isomers however 2 are favoured. Draw the structures of A-D and the 2 major stereoisomers of D.
Reaction Mechanisms: Synthesis
Design two syntheses, questions 1 and 2 from the indicated starting material. In addition, you can to use any hydrocarbon with three or fewer carbon atoms, any solvents or inorganic reagents, and any organic reagents that do not contribute carbon atoms to the carbon skeleton in the product. More than one step will be required for each synthesis. Show the required reagents and the product of each step but not the mechanisms.
