How many more stable carbocations are possible after rearrangement in the following carbocation.

How many more stable carbocations are possible after rearrangement in the following carbocation.

Why tirtary carbocations are more stable than, secondary and primary carbocations? Explain.

Carbocations are species in which central carbon carries positive charge. If the charge on the carbocations gets cocentrated or lo-calized the carbocation becomes unstable. The two factors which account for stability of carbocations are inductive effect and hyper conjugation (no bond resonance). Inductive effect is minor factor and hyper conjugation is major factor. Hybridisation of carbon in carbocation is
