Question 14.3: Draw structural formulas for the alkenes formed by the acid-...

Draw structural formulas for the alkenes formed by the acid-catalyzed dehydration of each alcohol. For each part, predict which alkene will be the major product. (a) 3-Methyl-2-butanol               (b) 2-Methylcyclopentanol

Strategy
In the acid-catalyzed dehydration of an alcohol, H and OH are removed from adjacent carbon atoms. When dehydration yields isomeric alkenes, the alkene with the greater number of alkyl groups on the carbon atoms of the double bond generally predominates
