Are carbocations necessarily sp2 hybridized and trigonal planar?

Carbonium ions can be thought of as protonated alkanes. Although alkanes are usually considered inert, under superacid conditions (e.g., HF/SbF5), the C-H sigma bond can act as a donor to H . This results in a species that contains a 3c-2e bond between a carbon and two hydrogen atoms, a type of bonding common in boron chemistry, though relatively uncommon for carbon. As an alt… WebTranscribed Image Text: The reaction shown in Figure 10-8 produces only one solvolysis product. Carbocation rearrangement does not occur because O the original carbocation is resonance stabilized.

WebRearrangement of a carbocation frequently involves an alkyl, phenyl, or hydride shift to the carbocation from an adjacent carbon (a 1,2-shift). In many cases, there are several different pathways by which rearrangement may take place. In these situations, the question of which group will migrate (migratory aptitude) is a complex one.
