Draw the mechanisms arrows that would show how the product is
formed in each elementary step. Make sure to draw the products of
the reaction and name the elementary reaction step(proton transfer,
sn2, coordination, heterolysis, e2, nucleophilic addition,
carbocation rearrangement, nucleophile elimination, electrophilic
addition, electrophile elimination).

Draw structures for all reactants and products, including correct stereochemistry (wedges and dashes). Show all the curved arrows in each step, and label each curved arrow according to whether it represents proton transfer, loss of a leaving group, nucleophilic attack, or carbocation rearrangement.

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...
