Alcohols are very useful organic compounds because there are many ways to synthesize larger and morecomplex molecules starting with simple alcohols. The reactions you will examine form a strong basis forsynthetic tools that an organic chemist would use. You will be expected to predict the major products ofreactions under the conditions given. The key to doing this is to look carefully at the conditions andremember how those conditions affect the products. It is a good idea to have an index card file of thereactions as you learn them. Dehydration (loss of water) - There are two forms of dehydration reactionswith alcohols - ether formation and elimination (alkene formation). In both reactions you are looking forthe components of water (OH and H) that will be removed in the reaction. Ether Formation - Two alcoholswill form an ether link by loss of water forming an ether product with an acidic catalyst (typically H2SO4) at140\deg C. One alcohol loses the hydroxyl group and one loses the H from its hydroxyl group. There areways of predicting which will lose which, but that is not important now. Ethers can be formed from twomolecules of the same alcohol or two different alcohols. When you have two different alcohols you usuallyget a mixture of the possible ethers. How many possibilities would there be ?

To predict the product you must have a hydrogen atom available on a carbonnext to the carbon with the hyroxy group. A double bond then forms from the carbon thatloses the hydroxyl group and the carbon that loses the hydrogen. Again, the reactiontakes place with an acid catalyst, but this time at 180°C.H₂SO,180 CPredict the product from the following conditions.HSO4|H H H180 CHHHHHH₂SO4H H140 C+HOA complication arises when you have more than one hydrogen to remove to form thealkene.

We areonly interested in one per carbon because the others are the same. If we remove thecircled hydrogen labeled A, we get the top alkene (2-butene) with 2 methyl groups. If weremove the circled hydrogen labeled B, we get the bottom alkene (1-butene) with an ethylgroup. The top alkene is favored because it has 2 alkyl groups attached to the double-bonded carbons and the other choice caly has one.+HOPredict the major product under these conditions.H-C CA)HB)H H30--CHCH, HPredict the products of the following reactions:H-HHH H H HHC-C-HCH₁ HH-904180 CC) (harder, but you can do it!)CH;HOH&HHH-804Alcohol Reactions, p. 4 of 4180 CH₂SO4H₂SO4+=140 C180 C
