Carbocations are stabilized by hyperconjugation but only high order. Primary ones are NOT. They are highly unstable Canbanions, on the other hand are stabilized by conjugation. Resonance can stabilize these ions, esp if aromatically Solution Carbocations are stabilized by hyperconjugation but only high order. Primary ones are NOT.
