Alcohols are very useful organic compounds because there are many ways to synthesize larger and more complex molecules starting with simple alcohols. The reactions you will examine form a strong basis for synthetic tools that an organic chemist would use. You will be expected to predict the major products of reactions under the conditions given. The key to doing this is to look carefully at the conditions and remember how those conditions affect the products. It is a good idea to have an index card file of the reactions as you learn them. Dehydration (loss of water) - There are two forms of dehydration reactions with alcohols - ether formation and elimination (alkene formation). In both reactions you are looking for the components of water (OH and H) that will be removed in the reaction. Ether Formation - Two alcohols will form an ether link by loss of water forming an ether product with an acidic catalyst (typically H2SO4) at 140\deg C. One alcohol loses the hydroxyl group and one…
