3) Name two solvents that are commonly used for SN2 reactions.
because they considerably slow down SN1 reactions.
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...

The dehydration of alcohols Under acidic conditions, alcohols will undergo a dehydration reaction, producing an alkene and water. During the reaction, the hydroxyl group of the alcohol and a hydrogen atom from an adjacent carbon atom are lost. The reaction takes place in three steps, as shown in the diagram. (Figure 1) In the first step, a hydrogen lon bonds to the hydroxyl group of the alcohol. In the second step, the protonated hydroxl group leaves the compound,...
