Concept:A carbocation is stabilized by electron donation from adjacent filled orbitals via resonance and hyperconjugation.Explanation:The empty p orbital of the carbocation interacts with neighboring filled π orbitals (resonance). It also interacts with filled σ orbitals (hyperconjugation) from adjacent C–H or C–C bonds. Both filled π and filled σ orbitals donate electron density to stabilize the positive charge.
