Benzyl> allyl > 3 ∘ > 2 ∘ >1 ∘. Nothing beats the stability of aromatic cations like cyclopropenium and cycloheptatrienylium (tropylium) cations. This is because alkyl groups are weakly electron donating due to hyperconjugation and inductive effects.resonance effects can further stabilise carbocations when a adjacent π system is present (delocalisation of charge is a stabilising.

I challenge you to draw out resonance for the systems below and verify the substitution on the yellow highlighted carbon atom. This means that a primary allylic carbocation, while stable, is still less stable compared to a secondary which is less stable when compared to a tertiary allylic pi bond. From experimental evidence, we have come to know that 3 o carbocation is more stable and need lower activation energy for its formation. (most stable) 3 o > 2 o > 1 o > methyl (least stable).

Next to this species is the 2 o carbocation is more stable than 1o carbocation and requires less activation energy than 1 o species. Because the hydride took the bond electrons, the carbon where the h migrated from becomes the new carbocation. Therefore a primary vinylic carbocation is. The product is then formed by nucleophilic attack at the new, more.
