6. Tertiary carbocations are relatively stable due to hyperconjugation. However, hyperconjugation has two basic requirements. The carbocation must be sp 2 hybridized (trigonal planar with an empty p orbital) and the adjacent σ bond network must be able to align itself parallel with the

Unformatted text preview: empty p orbital. Due to the rigid nature of this cyclic system, the carbocation is unable to rehybridize to sp 2 and therefore remains with an empty sp 3 orbital. As is typical with this hybridization, most of the orbital density lies on the side pointing out (white orbital in the right structure above), and therefore overlap (and stabilization) with the parallel sigma bonds (shown in gray) is minimal....
