Rank the alkyl halides in order of increasing SN2 reactivity. Br Br Br Increasing S2 reactivity

Alcohols and ethers are more reactive to substitution and elimination reactions under acidic conditions (compared to basic or neutral conditions). Draw the product of the reaction of the molecule shown with a strong acid. O ² ⒸO +1 Which structure from Part 1 would have a better leaving group: the reactant or the product? Choose one: O A. The product would have a better leaving group. OB. The reactant would have a better leaving group. C. Neither structure would have a good leaving group. O D. Both structures have equally good leaving groups. Draw the expected product when the protonated alcohol (the product) from part one reacts with iodide ion. DOC 20+1 H CI Br H C F P Cl Br I
