311 7.11 CARBOCATION STABILITY PRACTICE PROBLEM 7.18 When the compound called isoborneol is heated with 9 M sulfuric acid, the product of the reaction is the compound called camphene and not bornylene, as one might expect. Using models to assist you, write a step-by-step mechanism showing how camphene is formed. HO H,O+ not heat Bornylene Camphene Isoborneol 7.11B Rearrangement After Dehydration of a Primary Alcohol Rearrangements also accompany the dehydration of primary alcohols. Since a primary car- bocation is unlikely to be formed during dehydration of a primary alcohol, the alkene that is produced initially from a primary alcohol arises by an E2 mechanism, as described in Section 7.10C. However, an alkene can accept a proton to generate a carbocation in a process that is essentially the reverse of the deprotonation step in the El mechanism for dehydration of an alcohol (Section 7.10A). When a terminal alkene does this by using its nt electrons to bond o terminal carbon, a carbocation forms at the second carbon of the chain." Formation of a Rearranged Alkene Primary Alcohol
