= Carbocation
{wiki}
A <carbocation> is a positively charged carbon-containing species with the positive charge associated with its carbon framework. A classical three-coordinate carbenium center has an electron-deficient carbon and an available acceptor orbital.
Resonance, hyperconjugation, and neighboring groups can stabilize or redistribute the charge. The resulting reactivity includes nucleophilic capture and possible rearrangement; a drawn localized charge need not describe the complete electronic structure.
