Question 28 1 pts Imagine that a scientist mixes bromoethane and sodium tert-butoxide in 2-methyl-2-propanol. What type of reaction is likely to predominate? Remember to consider the type of alkyl halide that is involved, and remember also to consider whether the anion will act predominantly as a base or as a nucleophile or as both a base and a nucleophile. If the latter, consider the figure below to guide your decision. Finally, remember to consider the Apka rule, as it...

8) Draw a mechanism with all the proper arrows for the reaction
from this experiment.
Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile while the leaving group departs with both...
