3. Additional question. Propose a mechanism for the following reaction. You don't have to draw all resonance forms, but some important resonance forms should be shown. Hints: the mechanism involves two sequential carbocation rearrangements and a spirocyclic carbocation intermediate. H2SO4 heat (rac) OH
16. Draw the mechanism and product for the following elimination. OH conc. H2SO4 heat
29. Give the curved arrow mechanism for each reaction. DOH H2SO4, H,O heat F H2SO4, H2O . х арин OH H SOHO heal 30. For the following reaction, OH H,SO,H,O heat a. Draw the curved arrow mechanism. b. Use the mechanism to explain why acid is a catalyst in the dehydration reaction. C. Draw the energy diagram.

Practice Problem 07.70b Draw the mechanism for the following reaction: conc. H2SO4 Heat "OH
8.34 Draw a mechanism for each of the following E1 processes: OH Br conc. H2SO4 Heat БЕТОН Heat (b) EtOH. Her (C) ОН conc. H2SO4 Heat OPUS (d) D
For the following reaction, which reaction will be faster (Left or Right)? Why? Click on the reaction that will be faster AND the right reason Br +CH OH — ory Br + CH, OH Left Right Because the correct reaction is SN1 and the incorrect reaction is E1. Substitution reactions are more stable than elimination reactions Because the correct reaction doesn't have a double bond. Double bonds make unstable carbocations Because the correct reaction has resonance. The resonance structures allow...
37. H0+ (CH3), C CH OH alkene + H2O Draw the structure of the major alkene product of this acid-catalyzed dehydration. (Hint: rearrangement.) 38. alkenes Three alkenes produce butane when treated with hydrogen and platinum. Draw their structures. + H-Br - 39. CH2=CH CH3 CH2-CH-CH, H Br The first step of the mechanism of this reaction produces two carbocations. Draw both and circle the one that is more stable. ODHO Br 11 =C + Br - Br - - Br...
