Explain the result of the following reactions. Use arrow pushing and specify mechanistic types.
In-Class Arrow Pushing Activity Provide the appropriate arrow pushing for the following reactions and identify the arrow- pushing pattern(s) utilized as either loss of a leaving group, nucleophilic attack, proton transfer, or rearrangement. А : NH3 CH, :Br: H2O: :OH (4 steps)
Provide detailed mechanisms for each of the following reactions. Be certain to use arrow pushing (electron pushing) and to draw out all intermediates. If an intermediate is resonance stabilized, draw the most stable resonance contributor. H2SO4 a) heat CH3 нс 1 HI Ное heat c)

Draw the curved arrow mechanism to show the conversion of hex-1-ene and CHyOH in acid solution into 2- methoxyhexane. Follow the instructions under the boxes for each step. Draw all necessary atoms and charges, do not add any structures. Add any necessary atoms and charges to the carbon structures above to show the proper mechanistic intermediates and draw curved arrows to show the next mechanistic steps. Draw aurved arrows above....
